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.

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''' '

1	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'''' '

1	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 the section called “Defining 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 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

‘ ””

JDBC and ODBC syntax

followed by four single quotes. There is no space between the
four single quotes and the beginning of the time
format.

time_format

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 value

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 PBODB170 initialization file. If no time format is found in the PBODB170 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 PBODB170 initialization file. If no time
format is found in the PBODB170 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

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:

PowerBuilder

hh:mm

1

hh:mm
Application

Type the following in code:

PowerBuilder

SQLCA.DBParm="Time=' '''hh:mm''' '"

1

SQLCA.DBParm="Time=' '''hh:mm''' '"

What happens

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

UPDATE WORKHOURS
SET START='08:30'

1 2	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:

PowerBuilder

SQLCA.DBParm="Time=' ''''hh:mm'''' '"

1

SQLCA.DBParm="Time=' ''''hh:mm'''' '"

What happens

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

UPDATE WORKHOURS
SET START='08:30'

1 2	UPDATE WORKHOURS SET START='08:30'
