A month ago I had a talk about “Extending the Oracle Data Dictionary for Fine-Grained PL/SQL and SQL Analysis” during the ODTUG Kscope13 conference in New Orleans. Oracle data dictionary views as DBA_IDENTIFIERS or DBA_DEPENDENCIES are in many cases sufficient to analyze static PL/SQL and SQL code within the Oracle database. But what if more detailed analysis are required, such as the use of tables or columns in PL/SQL package units, in SQL statements or in SQL statement clauses? Wouldn’t a DBA_OBJECT_USAGE view – showing DML and query operations on tables/views per database object – be a helpful tool?
TVDCA – the Trivadis PL/SQL and SQL CodeAnalyzer – is such a tool and helps you to overcome several analysis restrictions in an Oracle 10g, 11g or 12c database. At Kscope13 some of my attentive session attendees got an USB stick with TVDCA 0.4.1 Beta. In the meantime I was busy fixing bugs to proudly present you now an updated trial/preview version free of charge in the download section of this blog.
The following query might give you an idea of the functionality of tvdca:
SQL> SELECT object_name, procedure_name, operation, table_name, column_name 2 FROM tvd_object_col_usage_v 3 WHERE owner = 'TVDCA' 4 AND object_type = 'PACKAGE BODY'; OBJECT_NAME PROCEDURE_NAME OPERATION TABLE_NAME COLUMN_NAME -------------- -------------- --------- -------------------- ---------------- TVD_COLDEP_PKG GET_DEP SELECT DBA_DEPENDENCIES NAME TVD_COLDEP_PKG GET_DEP SELECT DBA_DEPENDENCIES OWNER TVD_COLDEP_PKG GET_DEP SELECT DBA_DEPENDENCIES REFERENCED_NAME TVD_COLDEP_PKG GET_DEP SELECT DBA_DEPENDENCIES REFERENCED_OWNER TVD_COLDEP_PKG GET_DEP SELECT TVD_PARSED_OBJECTS_V OBJECT_NAME TVD_COLDEP_PKG GET_DEP SELECT TVD_PARSED_OBJECTS_V OBJECT_TYPE TVD_COLDEP_PKG GET_DEP SELECT TVD_PARSED_OBJECTS_V OWNER TVD_COLDEP_PKG PROCESS_VIEW SELECT DBA_TAB_COLUMNS COLUMN_ID TVD_COLDEP_PKG PROCESS_VIEW SELECT DBA_TAB_COLUMNS OWNER TVD_COLDEP_PKG PROCESS_VIEW SELECT DBA_TAB_COLUMNS TABLE_NAME
