cvs commit: jakarta-ant/src/testcases/org/apache/tools/ant/taskdefs SQLExecTest.java
sbailliez 01/12/21 16:04:12
Added: src/testcases/org/apache/tools/ant/taskdefs SQLExecTest.java
Log:
This testcase might be used to test for various problems
that may arise when calling the <sql> task multiple
times. I tried to make it easy to customize the test
to run it on different databases.
