Version 8 of tcl sqlite examples

Some examples of tcl and sqlite usage:

NOTE: the name of the database is opendb

• Retrieve the names of the tables stored in a sqlite database:

   set tableNames [opendb eval {SELECT tbl_name FROM sqlite_master}]
puts $tableNames

• Retrieve the names of the columns tored in a sqlite database(variable columnName):

   opendb eval "SELECT * FROM $tableName LIMIT 1" x {set columnName $x(*)} 
puts $columnName

jnc You can also use the PRAGMA statement table_info(table_name) to retrieve column information. See http://sqlite.org/pragma.html for a list of all PRAGMA statements.

• Retrieve the row data from a table

opendb eval "Select * FROM $i" values {set rowData $values(*)} 
foreach a $rowData {set rowList "$values($a)"}
puts $rowValues
