Why? If it is a variable you can define it in any way you want, no?

Or is it some external input you need to use? In this case: how did it get into this variable? Perhaps there is a better way to put it in more suitably formed variables. You might want to present the whole problem, not just an arbitrary part of it.

In this case how to use the array please?
The following is not pretty and less readable than my original idea, but there you go:

Code:
#! /bin/ksh

table_name="table1,table2,table3"
col_name=col1,col2,col3
table=""
col=""

while [ "$table_name" != "" ] ; do
     table="${table_name%%,*}"
     col="${col_name%%,*}"

     echo "TABLE: $table    COL: $col"

     table_name="${table_name##${table}}"
     col_name="${col_name##${col}}"
     table_name="${table_name##,}"
     col_name="${col_name##,}"
done

I hope this helps.

SQLITE_FETCH_COLUMN_TYPES(3)											      SQLITE_FETCH_COLUMN_TYPES(3)

sqlite_fetch_column_types - Return an array of column types from a particular table

SYNOPSIS
array sqlite_fetch_column_types (string $table_name, resource $dbhandle, [int $result_type = SQLITE_ASSOC]) DESCRIPTION
Object oriented style (method): array SQLiteDatabase::fetchColumnTypes (string $table_name, [int $result_type = SQLITE_ASSOC]) sqlite_fetch_column_types(3) returns an array of column data types from the specified $table_name table. PARAMETERS
o $table_name - The table name to query. o $dbhandle - The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the object-oriented method. o $result_type - The optional $result_type parameter accepts a constant and determines how the returned array will be indexed. Using SQLITE_ASSOC will return only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers). SQLITE_ASSOC is the default for this function. RETURN VALUES
Returns an array of column data types; FALSE on error. The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration option. CHANGELOG
+--------+--------------------+ |Version | | | | | | | Description | | | | +--------+--------------------+ | 5.1.0 | | | | | | | Added $result_type | | | | +--------+--------------------+ EXAMPLES
Example #1 Procedural example <?php $db = sqlite_open('mysqlitedb'); sqlite_query($db, 'CREATE TABLE foo (bar varchar(10), arf text)'); $cols = sqlite_fetch_column_types('foo', $db, SQLITE_ASSOC); foreach ($cols as $column => $type) { echo "Column: $column Type: $type "; } ?> Example #2 Object-oriented example <?php $db = new SQLiteDatabase('mysqlitedb'); $db->query('CREATE TABLE foo (bar varchar(10), arf text)'); $cols = $db->fetchColumnTypes('foo', SQLITE_ASSOC); foreach ($cols as $column => $type) { echo "Column: $column Type: $type "; } ?> The above example will output: Column: bar Type: VARCHAR Column: arf Type: TEXT PHP Documentation Group SQLITE_FETCH_COLUMN_TYPES(3)
