#Ems sql manager select into variable code
The main disadvantage of these methods is that for every change in object types searched, the SQL code need to be changed. name LIKE '%' + '%' ORDER BY Schema_name, Object_name The ROUTINE_DEFINITION column contains the source statements that created the function or stored nvarchar( 50 ) SET = SELECT DISTINCT The INFORMATION_SCHEMA.ROUTINES view contains information about all stored procedures and functions in a database. Use SQL that queries the INFORMATION_SCHEMA.ROUTINES view to search for a specific parameter in all procedures.
When searching for objects in other database object types – functions, triggers, columns, etc., or in multiple database object types at the same time, the SQL shown above should be modified accordingly. The following SQL examples search for the specified text – the variable – in stored procedures. However, all of these methods include querying system objects. There are several methods that can be used. Searching for a database object name or object definition is a bit easier than searching for specific text. To search for other data types, such as time and datetime, a new code must be written. Another disadvantage is that it can be used to search for text data only. The drawbacks of this solution are: use of cursors, which are generally inefficient, high complexity, a lot of time needed for execution, even on small databases.
