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.
Applies to
ODBC
O90 Oracle9i
O10 Oracle 10g
ORA Oracle (for 11g and later)
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:
ODBC syntax
PowerBuilder parses the backslash followed by two single quotes (\'') as a single quote when it builds the SQL UPDATE statement:
Time=' \''time_format\'' '
Oracle syntax
PowerBuilder parses each set of four consecutive single quotes ('''') as a single quote when it builds the SQL UPDATE statement:
Time=' ''''time_format'''' '
|
Parameter |
Description |
|---|---|
|
' \''
' '''' |
ODBC syntax Type a single quote, followed by one space, followed by a backslash, followed by two single quotes. There is no space between the two single quotes and the beginning of the time format. Oracle syntax Type a single quote, followed by one space, followed by four single quotes. There is no space between the four single quotes and the beginning of the time format. |
|
time_format |
The time format you want PowerBuilder to use when it builds a SQL UPDATE statement to update a data source in the DataWindow painter. For more on display formats, see the the section called “Defining display formats” in Users Guide. |
|
\'' '
'''' ' |
ODBC syntax Type a backslash, followed by two single quotes, followed by one space, followed by a single quote. There is no space between the end of the time format and the backslash. Oracle syntax Type four single quotes, followed by one space, followed by a single quote. There is no space between the end of the time format and the four single quotes. |
Default value
The default value for Time depends on the DBMS you are accessing:
|
DBMS |
Date default value |
|---|---|
|
ODBC |
If no value is specified for the Time parameter, PowerBuilder looks for a time format in the section for your ODBC driver in the PBODB initialization file. If no time format is found in the PBODB initialization file, PowerBuilder uses the ODBC time format escape sequence. |
|
Oracle |
The default Oracle date format. For information, see your Oracle documentation. |
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:
hh:mm
Example 1 (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:
hh:mm
-
Application
Type the following in code:
SQLCA.DBParm="Time=' \''hh:mm\'' '"
What happens
PowerBuilder builds the following SQL UPDATE statement to update the table:
UPDATE WORKHOURS 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:
SQLCA.DBParm="Time=' ''''hh:mm'''' '"
What happens
PowerBuilder builds the following SQL UPDATE statement to update the table:
UPDATE WORKHOURS SET START='08:30'
