public List<String> checkStoredProcedure(String procName, String procCreate, String ddlMode, Connection connection, JDBCLogger logger, Map<String, Serializable> properties) throws SQLExceptionDescription copied from class:Dialect
Checks if a given stored procedure exists and is identical to the passed creation SQL.There are 3 cases to deal with, and actions to perform:
- the stored procedure doesn't exist, and must be created (create the stored procedure);
- the stored procedure exists but is not up to date (drop the old stored procedure and re-create it);
- the stored procedure exists and is up to date (nothing to do).
When there is nothing to do,
null
is returned. Otherwise the returned value is a list of SQL statements to execute. Note that the SQL statements will include also INSERT statements to be executed to remember the creation SQL itself.- Specified by:
