Class SQLUpdate

java.lang.Object
  snaq.db.SQLUpdate

public class SQLUpdate
extends Object

Command-line utility to send SQL commands to a database. This class is useful for creating a large number of database tables and/or records from a user-defined text file containing SQL commands. It relies on the ConnectionPoolManager class to assist with the creation of a connection to the database, which in turn requires the appropriate dbpool.properties file in the classpath.

     Usage: java snaq.db.SQLUpdate <poolnames> <input file> [<separator>]
 

where pool is the name of the connection pool as defined in the dbpool.properties file, input file is the name of the text file containing the SQL statements to be issued to the defined database, and separator is an optional parameter to specify a delimiter for the SQL statements in the file. If the separator is not specified then each line of the file is assumed to be a separate statement.

Note: comments are allowed in the input file by starting the line with either "#" or "--".
