NAME

6       SQL::SplitStatement::Tokenizer - A simple SQL tokenizer.
7

SYNOPSIS

9        use SQL::SplitStatement::Tokenizer qw(tokenize_sql);
10
11        my $query= q{SELECT 1 + 1};
12        my @tokens= tokenize_sql($query);
13
14        # @tokens now contains ('SELECT', ' ', '1', ' ', '+', ' ', '1')
15

DESCRIPTION

17       SQL::SplitStatement::Tokenizer is a simple tokenizer for SQL queries.
18       It does not claim to be a parser or query verifier. It just creates
19       sane tokens from a valid SQL query.
20
21       It supports SQL with comments like:
22
23        -- This query is used to insert a message into
24        -- logs table
25        INSERT INTO log (application, message) VALUES (?, ?)
26
27       Also supports '', "" and "\'" escaping methods, so tokenizing queries
28       like the one below should not be a problem:
29
30        INSERT INTO log (application, message)
31        VALUES ('myapp', 'Hey, this is a ''single quoted string''!')
32

API

34       tokenize_sql
35               use SQL::SplitStatement::Tokenizer qw(tokenize_sql);
36
37               my @tokens = tokenize_sql($query);
38               my $tokens = tokenize_sql($query);
39
40               $tokens = tokenize_sql( $query, $remove_white_tokens );
41
42           "tokenize_sql" can be imported to current namespace on request. It
43           receives a SQL query, and returns an array of tokens if called in
44           list context, or an arrayref if called in scalar context.
45
46           If $remove_white_tokens is true, white spaces only tokens will be
47           removed from result.

54           operators.
