Hi All
Im using WBIMB6, Im trying to use the following select Statemnet
The table name and Column Name are both variables
It is as followed

SET ExistedCode = 'XYZ' ;
SET TableName = Environment.Variables.Code_Table;
SET StandardTableName = nvironment.Variables.Standard_Table;
SET StandardFieldName = Environment.Variables.Standard_Field;

SET Environment.Variables.Standard[] =( SELECT ITEM ST.ID FROM Database.AL.{StandardTableName}AS ST WHERE Database.AL.{StandardTableName}.{StandardFieldName} = ExistedCode);

but this is not working, I tried Also:

SET Environment.Variables.Standard[] =( SELECT ITEM ST.ID FROM Database.AL.{StandardTableName}AS ST WHERE ST.{StandardFieldName} = ExistedCode);

it didnt work either
is it possible to give the column name as variable

thanks in advance

hi all
I found some work around to solve my problem, but I hope I can find better solution

SET Quotation =SUBSTRING('g''h' FROM 2 FOR 1); -- in order to have Quotation ='

SET SQL_STATMENT = 'SELECT ID FROM AL.' || StandardTableName ||' WHERE '|| StandardFieldName||' = '||Quotation||ExistedCode||Quotation ;

SET Environment.Variables.PASSTHRU_Standard[] =PASSTHRU(SQL_STATMENT);

as this statement returned the name value paire I had to do the following select to get the value only
SET Environment.Variables.Standard[]= (SELECT ITEM E.ID FROM Environment.Variables.PASSTHRU_Standard[] AS E);

I will be glad to hear better sugesstions
