SQLWays Testing Features

This article describes SQLWays testing options, their usage and output generated.

The databases supported are: Sybase Adaptive Server Enterprise, Oracle and Microsoft SQL Server.

Option TEST

There are two ways of specifying the option TEST when running SQLWays:

  1. /TEST - when running from command-line;
  2. TEST=Yes - in the [COMMON] section of the sqlways.ini or sqlways_wzd.ini.

Option TEST is used to generate the calling statements for procedures or functions converted either from scripts or from the database. If this option is set the conversion is not performed, only calling statements are generated. Please, refer to the following example:

Assume you have the source Sybase ASE procedure. If the TEST option is not specified the conversion to Oracle is as follows:

Table1

Sybase ASE Oracle
create procedure sp_proc
as
declare @x int
select @x= 2
GO
create or replace procedure sp_proc
as
v_x NUMBER(10,0);
BEGIN
v_x := 2;
END;

When the TEST option is ON the following calling statement is generated instead of the converted syntax:

Table2

Sybase ASEOracle
create procedure sp_proc
as
declare @x int
select @x= count (distinct col1)
from Tab1
return @x
GO
CALL sp_proc();

Option MAX_NUMBER_OF_TEST_CALLS

This option is additionally specified in [COMMON] section sqlways.ini or sqlways_wzd.ini.

Option MAX_NUMBER_OF_TEST_CALLS is used to specify the number of calling statements for procedures or functions converted either from scripts or from the database. Please, refer to the following example:

Table3

Sybase ASEOracle
create procedure sp_params_select
@par1 int,
@par2 date,
@par3 varchar(20)
as
DECLARE @var1 int
DECLARE @var2 date
DECLARE @var3 varchar(20)
begin

set @var2 = (SELECT tb.col2
from tab_sp_params_select tb,
tab_sp_params_select1 tb1
where tb.col1 = @par1
and tb.col2=tb1.col2)

set @var3 = (SELECT tb.col3
from tab_sp_params_select tb,
tab_sp_params_select1 tb1
where tb.col2 = @par2
and tb.col2=tb1.col2)

set @var1 = (SELECT tb.col1
from tab_sp_params_select tb,
tab_sp_params_select1 tb1
where tb.col3 = @par3
and tb.col2=tb1.col2)
end
CALL sp_params_select(1,null,'1');
CALL sp_params_select(1,null,'1');
CALL sp_params_select(2,null,'1');
CALL sp_params_select(3,null,'1');
CALL sp_params_select(4,null,'1');
CALL sp_params_select(5,null,'1');
CALL sp_params_select(6,null,'1');
CALL sp_params_select(7,null,'1');
CALL sp_params_select(8,null,'1');
CALL sp_params_select(9,null,'1');
CALL sp_params_select(10,null,'1');

CALL sp_params_select(1,TO_DATE('2010-11-01','YYYY-MM-DD'),'1');

CALL sp_params_select(1,null,'1');
CALL sp_params_select(1,null,'2');
CALL sp_params_select(1,null,'3');
CALL sp_params_select(1,null,'4');
CALL sp_params_select(1,null,'5');
CALL sp_params_select(1,null,'6');
CALL sp_params_select(1,null,'7');
CALL sp_params_select(1,null,'8');
CALL sp_params_select(1,null,'9');
CALL sp_params_select(1,null,'10');

Please note that there are three SELECT statements inside the SP that return result-sets based on the values specified through the parameters, while calling the SP. So, if together with SP there are selected tables that are referenced inside the SP, there is generated a set of calling statments based on the data extracted from the source database. Please consider the following table for the data stored in the table tab_sp_params_select used in the example above:

Table4

tab_sp_params_select data
1,2010-11-01,1
2,2010-11-01,2
3,2010-11-01,3
4,2010-11-01,4
5,2010-11-01,5
6,2010-11-01,6
7,2010-11-01,7
8,2010-11-01,8
9,2010-11-01,9
10,2010-11-01,10
11,2010-11-01,11
12,2010-11-01,12
13,2010-11-01,13
14,2010-11-01,14
15,2010-11-01,15
16,2010-11-01,16
17,2010-11-01,17
18,2010-11-01,18
19,2010-11-01,19
20,2010-11-01,20

As you can see only one parameter is used per each select statement. That is why there are generated three sections of calling statments, each with up to 10 statements inside, as the MAX_NUMBER_OF_TEST_CALLS option is set to 10 for this example. Only DISTINCT values are taken. That is why for column col2 only one date value is used and only one calling statement is generated. The rest values are added as the default.

DEFAULT values for option TEST

Each database has it's own set of data types, that can be specified differently from RDBMS to RDBMS. That is why the default values for TEST option are specified in their own database section. Please refer to the following table with the sections and options names and their values:
