DECLARE @SQL1 VARCHAR(MAX)
SET @SQL1='SELECT * FROM tblResponsibleEngineer WHERE ResponsibleEngineer='+CAST(@ResponsibleEngineer AS VARCHAR(500))+''
EXEC(@SQL1)
IF @@ROWCOUNT>0
BEGIN
SET @Result='EXIST'

above query fails execution due to the way i pass the parameter @ResponsibleEngineer in to the query. error is "Invalid column name TEST". TEST is the value i’m passing as the parameter value
@ResponsibleEngineer and there is no such column as TEST in the table.what the error when passing the parameter to insert query?

    You need speach marks around the Parameter:

    'SELECT * FROM tblResponsibleEngineer WHERE ResponsibleEngineer='''+CAST(@ResponsibleEngineer AS VARCHAR(500))+''''

    Otherwise you are generating:

    SELECT * FROM tblResponsibleEngineer WHERE ResponsibleEngineer=TEST'

    Therefore its looking for a column TEST. By having the parameter in speach marks you are generating:

    SELECT * FROM tblResponsibleEngineer WHERE ResponsibleEngineer='TEST'

    This query will then run a WHERE clause where the ResponsibleEngineer column equals the string value TEST
