.SH "DESCRIPTION"
.PP
As a convenience to database drivers, Tcl Database Connectivity (TDBC)
provides a command to break SQL code apart into tokens so that bound
variables can readily be identified and substituted.
.PP
The \fBtdbc::tokenize\fR command accepts as its parameter a string
that is expected to contain one or more SQL statements. It returns a
list of substrings; concatenating these substrings together will yield
the original string. Each substring is one of the following:
.IP [1]
A bound variable, which begins with one of the
characters '\fB:\fR', '\fB@\fR', or '\fB$\fR'. The
remainder of the string is the variable
name and will consist of alphanumeric characters and underscores. (The
leading character will be be non-numeric.)
.IP [2]
A semicolon that separates two SQL statements.
.IP [3]
Something else in a SQL statement. The tokenizer does not attempt to
parse SQL; it merely identifies bound variables (distinguishing them
from similar strings appearing inside quotes or comments) and
statement delimiters.
