+<P>This switch can be used to specify which SQL injection type to test for.
+By default sqlmap tests for <B>all</B> types/techniques it supports.</P>
+
+<P>In certain situations you may want to test only for one or few specific
+types of SQL injection thought and this is where this switch comes into
+play.</P>

+<P>This switch requires an argument. Such argument is a string composed by

+<CODE>T</CODE> characters where each letter stands for a different technique:</P>
