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. If you store 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. This will however 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.

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.
