Catalog stored procedures retrieve information from the system tables in tabular form. You can supply wildcard characters for some parameters.
sp_tables lists all user tables in a database when used in the following format:
sp_tables @table_type = "’TABLE’"
sp_columns returns the datatype of any or all columns in one or more tables in a database. You can use wildcard characters to get information about more than one table or column.
For example, the following command returns information about all columns that include the string “id” in all the tables with “sales” in their name:
sp_columns "%sales%", null, null, "%id%"
