Date

database parameter

Description

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

Applies to

JDB JDBC

ODBC

O90 Oracle9i

O10 Oracle 10g

ORA Oracle (for 11g and later)

Syntax

The syntax you use to specify the Date 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 date
format.

In a PowerBuilder application script, 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.

Date=' '''date_format''' '

1	Date=' '''date_format''' '

Oracle syntax

PowerBuilder parses each set of four consecutive single quotes
(””) as a single quote when it builds the SQL UPDATE statement.

Date=' ''''date_format'''' '

1	Date=' ''''date_format'''' '

Parameter	Description
‘ ”’ ‘ ””	JDBC and 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 date 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 date format.
date_format	The date 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 “Date display formats” in Users Guide.
”’ ‘ ”” ‘	JDBC and 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 date 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 date format and the four single quotes.

Default value

The default value for Date depends on the DBMS you are accessing,
as summarized in the following table:

DBMS	Date default value
JDBC	If no value is specified for the Date database parameter, PowerBuilder looks for a date format in the section for your JDBC driver in the registry. If no date format is found in the registry, PowerBuilder uses the JDBC date format escape sequence.
ODBC	If no value is specified for the Date database parameter, PowerBuilder looks for a date format in the section for your ODBC driver in the PBODB initialization file. If no date format is found in the initialization file, PowerBuilder uses the ODBC date format escape sequence.
Oracle	The default Oracle date format. For information, see your Oracle documentation.

DBMS

Date default value

JDBC

If no value is specified for the Date database
parameter, PowerBuilder looks for a date format in the section
for your JDBC driver in the registry. If no date format is found
in the registry, PowerBuilder uses the JDBC date format escape
sequence.

ODBC

If no value is specified for the Date database
parameter, PowerBuilder looks for a date format in the section
for your ODBC driver in the PBODB initialization file. If no
date format is found in the initialization file, PowerBuilder
uses the ODBC date format escape sequence.

Oracle

The default Oracle date format.

information, see your Oracle documentation.

Examples

About these examples

Assume you are updating a table named Employee by setting the
Startdate column to 2006-04-23. This date is represented by the
following date format:

yyyy-mm-dd

1	yyyy-mm-dd

Example 1 (JDBC and ODBC syntax)

To specify that PowerBuilder should use this format for the date
datatype when it builds the SQL UPDATE statement:

Database profile

Type the following in the Date Format box on the Syntax page
in the Database Profile Setup dialog box:

PowerBuilder

yyyy-mm-dd

1

yyyy-mm-dd
Application

Type the following in code:

PowerBuilder

SQLCA.DBParm="Date=' '''yyyy-mm-dd''' '"

1

SQLCA.DBParm="Date=' '''yyyy-mm-dd''' '"

What happens

PowerBuilder builds the following SQL UPDATE statement to update
the table:

UPDATE EMPLOYEE
SET STARTDATE='2006-04-23'

1 2	UPDATE EMPLOYEE SET STARTDATE='2006-04-23'

Example 2 (Oracle syntax)

To specify that PowerBuilder should use this format for the date
datatype when it builds the SQL UPDATE statement:

Database profile

Type the following in the Date format box on the Syntax page
in the Database Profile Setup dialog box:

PowerBuilder

yyyy-mm-dd

1

yyyy-mm-dd
Application

Type the following in code:

PowerBuilder

SQLCA.DBParm="Date=' ''''yyyy-mm-dd'''' '"

1

SQLCA.DBParm="Date=' ''''yyyy-mm-dd'''' '"

What happens

PowerBuilder builds the following SQL UPDATE statement to update
the table:

UPDATE EMPLOYEE
SET STARTDATE='2006-04-23'

1 2	UPDATE EMPLOYEE SET STARTDATE='2006-04-23'
