Modeler: 10/RepositorySql

SQL Repository

This window enables you to write advanced queries on the repository using sql. It uses the SQLite[1] syntax. On the left the panel shows various databases which may be queried, with their tables, views and the columns in them.

External Database

Dragging sqlite databases from the project panel into the database panel will mount them to be queried. Additionally any ODBC connection in the system is listed here. This allows any ODBC source to be integrated in CaseTalk through various queries.

The SQLite function set is extended with a few more functions, especially used inside CaseTalk:

md5

The md5 function generates a hash from the value passed as text.

 select 
 md5(otftname) as OTFT_HASH, OTFTName
 from otft;

macro

The macro function supports keywords also defined in the custom attribute keywords. An example query could be:

 select 
 macro('%PROJECTNAME%\%IGNAME%\v%IGVERSION%\' || otftname) as FULL_OTFT 
 from otft;

soundex

The soundex function returns a code for the text which allows text comparisons on the sound of them.

 select otftname, soundex(otftname) from otft

annotation

Extract the named annotation from a sectioned comment field. CaseTalk supports Custom Annotations, yet stores them in a single textblob. This function enables sql to extract the named annotation.

 select 
 otftname, 
 annotation('Comment', comment) as comment,
 annotation('Remarks', comment) as remarks
 from otft;

Registry

Fetch the registry entry value by the name as a simple function instead of a subselect in sql.

 select
   otftname as tablename,
   registry('Profile') as IG_Transformation
 from otft;

CustomAttribute

Fetch custom attribute value using a simple function instead of a long subquery.

 select
   otftname,
   customattributes('otft', otftname, 'source', 'modeler') as author
 from otft;
