entity framework 4 POCO's stored procedure error - "The FunctionImport could not be found in the container"
- by user331884
Entity Framework with POCO Entities generated by T4 template. Added Function Import named it "procFindNumber" specified complex collection named it "NumberResult".
Here's what got generated in Context.cs file:
public ObjectResult<NumberResult> procFindNumber(string lookupvalue)
{
ObjectParameter lookupvalueParameter;
if (lookupvalue != null)
{
lookupvalueParameter = new ObjectParameter("lookupvalue", lookupvalue);
}
else
{
lookupvalueParameter = new ObjectParameter("lookupvalue", typeof(string));
}
return base.ExecuteFunction<NumberResult>("procFindNumber", lookupvalueParameter);
}
Here's the stored procedure:
ALTER PROCEDURE [dbo].[procFindNumber]
@lookupvalue varchar(255)
AS
BEGIN
SET NOCOUNT ON;
DECLARE @sql nvarchar(MAX);
IF @lookupvalue IS NOT NULL AND @lookupvalue <> ''
BEGIN
SELECT @sql = 'SELECT dbo.HBM_CLIENT.CLIENT_CODE, dbo.HBM_MATTER.MATTER_NAME, dbo.HBM_MATTER.CLIENT_MAT_NAME
FROM dbo.HBM_MATTER INNER JOIN dbo.HBM_CLIENT ON dbo.HBM_MATTER.CLIENT_CODE = dbo.HBM_CLIENT.CLIENT_CODE
LEFT OUTER JOIN dbo.HBL_CLNT_CAT ON dbo.HBM_CLIENT.CLNT_CAT_CODE = dbo.HBL_CLNT_CAT.CLNT_CAT_CODE
LEFT OUTER JOIN dbo.HBL_CLNT_TYPE ON dbo.HBM_CLIENT.CLNT_TYPE_CODE = dbo.HBL_CLNT_TYPE.CLNT_TYPE_CODE
WHERE (LTRIM(RTRIM(dbo.HBM_MATTER.CLIENT_CODE)) <> '''')'
SELECT @sql = @sql + ' AND (dbo.HBM_MATTER.MATTER_NAME like ''%' + @lookupvalue + '%'')'
SELECT @sql = @sql + ' OR (dbo.HBM_MATTER.CLIENT_MAT_NAME like ''%' + @lookupvalue + '%'')'
SELECT @sql = @sql + ' ORDER BY dbo.HBM_MATTER.MATTER_NAME'
-- Execute the SQL query
EXEC sp_executesql @sql
END
END
In my WCF service I try to execute the stored procedure:
[WebGet(UriTemplate = "number/{value}/?format={format}")]
public IEnumerable<NumberResult> GetNumber(string value, string format)
{
if (string.Equals("json", format, StringComparison.OrdinalIgnoreCase))
{
WebOperationContext.Current.OutgoingResponse.Format = WebMessageFormat.Json;
}
using (var ctx = new MyEntities())
{
ctx.ContextOptions.ProxyCreationEnabled = false;
var results = ctx.procFindNumber(value);
return results.ToList();
}
}
Error message says "The FunctionImport ... could not be found in the container ..."
What am I doing wrong?
