In particular, the SYSCS_UTIL.SYSCS_CHECK_TABLE
function verifies the following conditions:
- Base tables are internally consistent
- Base tables and all associated indexes contain the same number of rows
- The values and row locations in each index match those of the base table
- All BTREE indexes are internally consistent
You run this function in an SQL statement, as follows:
VALUES SYSCS_UTIL.SYSCS_CHECK_TABLE(SchemaName, TableName)
where SchemaName and TableName are expressions that evaluate to a
string data type. If you created a schema or table name as a non-delimited
identifier, you must present their names in all upper case. For example:
VALUES SYSCS_UTIL.SYSCS_CHECK_TABLE('APP', 'CITIES')
The SYSCS_UTIL.SYSCS_CHECK_TABLE function returns a
SMALLINT. If the table is consistent (or if you run
SYSCS_UTIL.SYSCS_CHECK_TABLE on a view),
SYSCS_UTIL.SYSCS_CHECK_TABLE returns a non-zero value.
Otherwise, the function throws an exception on the first inconsistency that it
finds.
For a consistent table, the following result is displayed:
1
