Subject [jira] Resolved: (DERBY-337) dblook doesn't generate SQL statements for SQL functions.
Date Fri, 10 Jun 2005 15:51:47 GMT
     [ http://issues.apache.org/jira/browse/DERBY-337?page=all ]
     
A B resolved DERBY-337:
-----------------------

    Resolution: Fixed

Main patch was committed with svn revision 189650 and the followup patch was committed with
svn revision 189835.  However, current discussion on derby-dev suggests that I may have to
redo a small part of this patch to make it cleaner (see the thread here:  http://article.gmane.org/gmane.comp.apache.db.derby.devel/5362)

So I'm marking this issue as Resolved, but am not closing it until the above discussion thread
is finalized.

> DBLOOK schema dumping tool doesn't emit SQL statements for functions. It covers procedures
and all other database objects, but not funtions. Here is an example I tried:
> [bandaram:satheesh] java org.apache.derby.tools.dblook -d 'jdbc:derby:tdb'
> -- Timestamp: 2005-06-05 09:41:20.603
> -- Source database is: tdb
> -- Connection URL is: jdbc:derby:tdb
> -- appendLogs: false
> -- ----------------------------------------------
> -- DDL Statements for tables
> -- ----------------------------------------------
> CREATE TABLE "APP"."T" ("I" INTEGER);
> At this point, the database has only one table 'T'. Now create a function:
> C:\DerbyCode\bug>java -Dij.protocol=jdbc:derby: org.apache.derby.tools.ij
> ij version 10.1
> ij> connect 'tdb';
> ij> create function gatp(SCH VARCHAR(128), TBL VARCHAR(128)) RETURNS VARCHAR(100
> 0)
> EXTERNAL NAME 'org.apache.derbyTesting.functionTests.util.TestPropertyInfo.getAllTableProperties'
> LANGUAGE JAVA PARAMETER STYLE JAVA;
> 0 rows inserted/updated/deleted
> ij> quit;
> Now try dblook. Should show a function, but doesn't.
> [bandaram:satheesh] java org.apache.derby.tools.dblook -d 'jdbc:derby:tdb'
> -- Timestamp: 2005-06-05 09:41:20.603
> -- Source database is: tdb
> -- Connection URL is: jdbc:derby:tdb
> -- appendLogs: false
> -- ----------------------------------------------
> -- DDL Statements for tables
> -- ----------------------------------------------
> CREATE TABLE "APP"."T" ("I" INTEGER);
> Now create a procedure:
> C:\DerbyCode\bug>java -Dij.protocol=jdbc:derby: org.apache.derby.tools.ij
> ij version 10.1
> ij> connect 'tdb';
> ij> create procedure insertAsciiColumn( stmtText varchar( 256), colNumber int) P
> ARAMETER STYLE JAVA LANGUAGE JAVA MODIFIES SQL DATA
>   EXTERNAL NAME 'org.apache.derbyTesting.functionTests.util.StreamUtil.insertAsc
> iiColumn';
> 0 rows inserted/updated/deleted
> ij> 
> DBLOOK output include newly created procedure, but still not function statement.
> [bandaram:satheesh] java org.apache.derby.tools.dblook -d 'jdbc:derby:tdb'
