  • What is the best way of inserting a datetime value using dynamic sql

    - by jaffa
    What is the best way of inserting a datetime value using a dynamic sql string, whilst at the same time being able to handle the possibility of the value being null? The current statement inserts into a table from a select statement built using a string. The datetime value is stored in a parameter and the parameter is used in the select. Like so: set @execsql = 'Insert into ( start_date ) SELECT ( ''' + CAST(start_date as VARCHAR) + ''' + ')'

  • MySQLi Insert prepared statement via PHP

    - by Jimmy
    Howdie do, This is my first time dealing with MySQLi inserts. I had always used mysql and directly ran the queries. Apparently, not as secure as MySQLi. Anywho, I'm attempting to pass two variables into the database. For some reason my prepared statement keeps erroring out. I'm not sure if it's a syntax error, but the insert just won't work. I've updated the code to make the variables easier to read Also, the error is specifically, Error preparing statement. I've updated the code, but it's not a pHP error. It's a MySQL error as the script runs but fails at the execution of: if($stmt = $mysqli - prepare("INSERT INTO subnets (id, subnet, mask, sectionId, description, vrfId, masterSubnetId, allowRequests, vlanId, showName, permissions, pingSubnet, isFolder, editDate) VALUES ('', ?, ?, '1', '', '0', '0', '0', '0', '0', '{"3":"1","2":"2"}', '0', '0', 'NULL')")) { I'm going to enable MySQL error checking. I honestly didn't know about that. <?php error_reporting(E_ALL); function InsertIPs($decimnal,$cidr) { error_reporting(E_ALL); $mysqli = new mysqli("localhost","jeremysd_ips","","jeremysd_ips"); if(mysqli_connect_errno()) { echo "Connection Failed: " . mysqli_connect_errno(); exit(); } if($stmt = $mysqli -> prepare("INSERT INTO subnets (id, subnet, mask,sectionId,description,vrfld,masterSubnetId,allowRequests,vlanId,showName,permissions,pingSubnet,isFolder,editDate) VALUES ('',?,?,'1','','0','0','0','0','0', '{'3':'1','2':'2'}', '0', '0', NULL)")) { $stmt-> bind_param('ii',$decimnal,$cidr); if($stmt-> execute()) { echo "Row added successfully\n"; } else { $stmt->error; } $stmt -> close; } } else { echo 'Error preparing statement'; } $mysqli -> close(); } $SUBNETS = array ("2915483648 | 18"); foreach($SUBNETS as $Ip) { list($TempIP,$TempMask) = explode(' | ',$Ip); echo InsertIPs($Tempip,$Tempmask); } ?> This function isn't supposed to return anything. It's just supposed to perform the Insert. Any help would be GREATLY appreciated. I'm just not sure what I'm missing here

  • When not to use a private field

    - by coffeeaddict
    When should it be considered dangerous to use a private field all over the place in the methods of your class? I mostly just create the variable and set it to a default value like null. Then in my methods reference it and set it to an instance of that object type from the methods. I don't know if my question makes sense but let me know if it doesn't and I'll clarify.

  • In String.replace("\c","") what ASCII value is ""?

    - by Tom
    Hi, im just writing my own replace method for any weird characters and i used the ASCI value 0, null to replace unwanted characters, i was hoping for them to be 'deleted', but this doesnt work. A gap just appears in the string. What exactly does String.Replace() do when removing a character for ""? Does it shift them all down and then 'delete' the final character or something?

  • # character seems to cause problems with a get Request

    - by Ankur
    I have a queryString that I pass to a servlet's doGet() method that looks like this: count=9&preId0=-99&objId0=-99&preId1=-99&objId1=-99&preId2=69&objId2=16#!78&preId3=-99&objId3=-99&preId4=-99&objId4=-99&preId5=-99&objId5=-99&preId6=-99&objId6=-99&preId7=-99&objId7=-99&preId8=-99&objId8=-99 After and including the # everything is null, so I am assuming the # has some special meaning. Is this true? and are there other such characters that will do this?

  • Unable to use getInt() but able to use getString() for a sqlite database

    - by mwrazam
    I am using a cursor to access a sqlite database I have in my app. I am having trouble using the .getInt() on my database. My database is pre-created, and I have a few cursors that perform queries to interface with the information. Several of the columns in one of the tables are set as INTEGER type. I realize that sqlite has no built in check to make sure columns are indeed INT. However, when retrieving the data, I can use the .getString() function without any issues, but calling .getInt() causes the app to crash. Below is the relevant code. If I am missing anything, please let me know, and I'll add it in. Any help is greatly appreciated. Thank you very much. Cursor: public Cursor getSkitStats(int module, int skit) { Cursor mCursor = myDataBase.rawQuery("SELECT * FROM score WHERE mod="+module+" AND skit="+skit+"", null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } and I am using a simple Toast call to output the result of the query: Toast.makeText(getApplicationContext(), scoreContent.getInt(0), Toast.LENGTH_SHORT).show(); The variable scoreContent is the cursor. And here is the crash output: 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Handler.dispatchMessage(Handler.java:99) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Looper.loop(Looper.java:130) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invokeNative(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invoke(Method.java:507) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-08 23:53:31.726: E/AndroidRuntime(15685): at dalvik.system.NativeStart.main(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x2 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.content.res.Resources.getText(Resources.java:205) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.widget.Toast.makeText(Toast.java:258) 07-08 23:53:31.726: E/AndroidRuntime(15685): at jp.atomicideas.ne.Summary.onCreate(Summary.java:90) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 07-08 23:53:31.726: E/AndroidRuntime(15685): ... 11 more

  • DateTime Formatting in repeater

    - by Krishna
    Hi, I am trying to format the date time (yyyy/MM/dd) in a repeater which is binded to an ObjectDataSource as shown (THIS WORKS) <%# ((MyType)Container.DataItem).CreateDateTime.ToString("yyyy/MM/dd")% (THIS DOES`NT WORKS) <%# String.Format("{0:yyyy/MM/dd}",((MyType)Container.DataItem).UpdateDateTime)% I want to have both things working because sometimes the property UpdateDateTime is null, in such cases the second line of code handles smart. Thank you for the help in advance.

  • Combine First, Middle Initial, Last name and Suffix in T-SQL (No extra spaces)

    - by Paul
    I'm trying not to reinvent the wheel here...I have these four fields [tbl_Contacts].[FirstName], [tbl_Contacts].[MiddleInitial], [tbl_Contacts].[LastName], [tbl_Contacts].[Suffix] And I want to create a FullName field in a view, but I can't have extra spaces if fields are blank...So I can't do FirstName + ' ' + MiddleInitial + ' ' + LastName + ' ' + Suffix...Because if there is no middle initial or suffix I'd have 2 extra spaces in the field. I think I need a Case statement, but I thought someone would have a handy method for this...Also, the middleinitial and suffix may be null.

  • Will my shared variables loose value? (asp.net vb)

    - by Phil
    I have a class includes.vb that holds some variables (sharing them with other pages) like: Public Shared pageid As Integer = 0 I then have a function that does some work with these variables returning them with values; Return pageid When I step through the code, the variables have values (while stepping through the function), but when they are returned to the page, they come back null. Do they loose value everytime a page is loaded? Can you suggest an alternative method? Thanks a lot.

  • How to check total cache size using a program

    - by user1888541
    so I'm having some trouble creating a program to measure cache size in C. I understand the basic concept of going about this but I'm still having trouble figuring out exactly what I am doing wrong. Basically, I create an array of varying length (going by power of 2s) and access each element in the array and put it in a dummy variable. I go through the array and do this around 1000 times to negate the "noise" that would otherwise occur if I only did it once to get an accurate measurement for time. Then, I look for the size that causes a big jump in access time. Unfortunately, this is where I am having my problem, I don't see this jump using my code and clearly I am doing something wrong. Another thing is that I used /proc/cpuinfo to check the cache and it said the size was 6114 but that was not a power of 2. I was told to go by powers of 2 to figure out the cache can anyone explain why this is? Here is the just of my code...I will post the rest if need be { struct timeval start; struct timeval end; // int n = 1; // change this to test different sizes int array_size = 1048576*n; // I'm trying to check the time "manually" first before creating a loop for the program to do it by itself this is why I have a separate "n" variable to increase the size char x = 0; int i =0, j=0; char *a; a =malloc(sizeof(char) * (array_size)); gettimeofday(&start,NULL); for(i=0; i<1000; i++) { for(j=0; j < array_size; j += 1) { x = a[j]; } } gettimeofday(&end,NULL); int timeTaken = (end.tv_sec * 1000000 + end.tv_usec) - (start.tv_sec *1000000 + start.tv_usec); printf("Time Taken: %d \n", timeTaken); printf("Average: %f \n", (double)timeTaken/((double)array_size); }
