But the sp_executesql statement provides a better way of implementing this. If we are using EXECUTE command to execute the SQL String, then all the parameters should be converted to character and made as a part of the Query before execution. Sp_executesql which is more efficient, faster in execution and also supports parameter substitution. NOTE: Most importantly, the Dynamic SQL Queries in a variable are not compiled, parsed, checked for errors until they are executed.Ī dynamically build Transact-SQL statements can be executed using EXECUTE Command or sp_executesql statement. Say for example - An employee search screen or a general purpose report which needs to execute a different SELECT statement based on a different WHERE clause. A Dynamic SQL is needed when we need to retrieve a set of records based on different search parameters. "When to Use Dynamic SQL?" We can't definitely say that a Static SQL will meet all our programming needs. ![]() There may be several methods of implementing this in SQL Server. A dynamic SQL in a stored procedure is a single Transact-SQL statement or a set of statements stored in a variable and executed using a SQL command.
