  • False

Syntax

Use cli.pkg
Get_Attribute DF_DATABASE_TRUNCATE_BINARY_ZEROES of {driverNumber} {databaseHandle} to {BooleanVariable}
Set_Attribute DF_DATABASE_TRUNCATE_BINARY_ZEROES of {driverNumber} {databaseHandle} to {True|False}

Driver Configuration Keyword

Truncate_Binary_Zeroes

Remarks

Some back-ends will return binary data completely filled out with binary zeroes. For example, if you store the hex value AE003400 in a column of 6 positions, you would see AE0034000000 when retrieving the column.

It is possible to switch on truncation of trailing binary zeroes. However, this will also truncate trailing zeroes that are actually part of the column value. Storing the hex value AE003400 in a column of 6 positions would give AE0034 when retrieving the column.

You can turn on truncating of trailing zeroes by setting this attribute to true.

Example

Procedure ShowDBAttribute Integer iDriver Handle hDatabase
    Boolean bAttribValue
    Get_Attribute DF_DATABASE_TRUNCATE_BINARY_ZEROES of iDriver hDatabase to bAttribValue
    Showln "Truncate trailing zeroes: " (If(bAttribValue, "YES", "NO"))
End_Procedure

The sample code above shows the current setting for a given database. The database handle can be obtained via the DF_DATABASE_ID attribute.
