Time

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

JDB JDBC
ODBC
O90 Oracle9i
O10 Oracle 10g
ORA Oracle 11g

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:

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
' \'' ' ''''	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 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 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 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.

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 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 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 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

The default value for Time depends on the DBMS you are accessing:

DBMS	Date default value
JDBC	If no value is specified for the Time parameter, PowerBuilder looks for a time format in the section for your JDBC driver in the registry. If no time format is found in the registry, PowerBuilder uses the JDBC time format escape sequence.
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 PBODB125 initialization file. If no time format is found in the PBODB125 initialization file, PowerBuilder uses the ODBC time 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 Time parameter, PowerBuilder looks for a time format in the section for your JDBC driver in the registry. If no time format is found in the registry, PowerBuilder uses the JDBC time format escape sequence.

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 PBODB125 initialization file. If no time format is found in the PBODB125 initialization file, PowerBuilder uses the ODBC time format escape sequence.

Oracle

The default Oracle date format.

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 (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:
```
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'
