Time database parameter
Description
When you update data in the DataWindow painter, PowerBuilder builds
a SQL UPDATE statement
in the background. The Time parameter determines how PowerBuilder specifies
a time datatype when it builds the SQL UPDATE statement.

Syntax
The syntax you use to specify the Time parameter differs slightly
depending on the database.
The Database Profile Setup dialog box inserts special characters
(quotes and backslashes) where needed, so you can specify just the
time format.
In code, you must use the following syntax:
[JDBC and ODBC syntax]
PowerBuilder parses the backslash followed by two single quotes
(”’) as a single quote when it builds
the SQL UPDATE statement:
1 |
Time=' '''<span>time_format</span>''' ' |
[Oracle syntax]
PowerBuilder parses each set of four consecutive single quotes
(””) as a single quote when
it builds the SQL UPDATE statement:
1 |
Time=' ''''<span>time_format</span>'''' ' |

Examples
About these examples
Assume you are updating a table named Workhours by setting
the Start column to 08:30. This time is represented by the following PowerBuilder time
format:
1 |
hh:mm |
Example 1 (JDBC and ODBC syntax)
To specify that PowerBuilder should use this format for the
time datatype when it builds the SQL UPDATE statement:
-
Database profile
Type the following in the Time Format box on the Syntax page
in the Database Profile Setup dialog box:1hh:mm -
Application
Type the following in code:
1SQLCA.DbParameter="Time=' '''hh:mm''' '"
What happens PowerBuilder builds
the following SQL UPDATE statement
to update the table:
1 |
UPDATE WORKHOURS |
1 |
SET START='08:30' |
Example 2 (Oracle syntax)
To specify that PowerBuilder should use this format for the
time datatype when it builds the SQL UPDATE statement:
-
Database profile
Type
hh:mm
in the Time
Format box on the Syntax page in the Database Profile Setup dialog
box. -
Application
Type the following in code:
1SQLCA.DbParameter="Time=' ''''hh:mm'''' '"
What happens PowerBuilder builds
the following SQL UPDATE statement
to update the table:
1 |
UPDATE WORKHOURS |
1 |
SET START='08:30' |
