Applies to: Oracle, MS SQL, MySql/MariaDB, PostgreSQL Drivers

Syntax

f2s_write_trace_ln  {output line}

Description

This command inserts a string into the trace file when tracing is enabled. Using f2s_write_trace_ln is a good way to study particular problems you encounter in the driver. f2s_write_trace_ln allows you to insert sections of your code into the trace file. This command can also set the trace to three different levels, allowing different amounts of information to be logged. Note that trace files can become very large so it is good practice to only turn them on when specifically needed.

Example

 String sTableName
 Boolean bTableExists
 f2s_trace_on to "C:\Users\[USERNAME]\Documents\log.txt" DETAIL_LEVEL3
 f2s_check_sql_table_exists  "Customer" "dbo" "OrderEntry" to bTableExists
 f2s_write_trace_ln ("Customer Table exists:" * String(bTableExists))
 f2s_trace_off
