Package org.ametys.core.script

Class SQLScriptHelper

java.lang.Object

org.ametys.core.script.SQLScriptHelper

public final class SQLScriptHelper
extends Object

Example of simple use: SQLScriptHelper.createTableIfNotExists(dataSourceId, "QRTZ_JOB_DETAILS", "plugin:core://scripts/%s/quartz.sql", _sourceResolver); Will test if table QRTZ_JOB_DETAILS exits in database from datasource dataSourceId. If not, the script plugin:core://scripts/%s/quartz.sql will be resolved and executed (where %s is replaced by the database type 'mysql', 'derby'...) Tools to run SQL scripts.

Default separator for isolating statements is the semi colon character: ;.
It can be changed by using a comment like the following snippet for using the string ---:
-- _separator_=---
begin
execute immediate 'DROP TABLE MYTABLE';
Exception when others then null;
end;
---
-- _separator_=;
CREATE TABLE MYTABLE;
...
Note that the command must be placed at the end of the comment.

The runner can be configured to ignore SQLExceptions. This can be useful to execute DROP statements when it's unknown if the tables exist:
--_ignore_exceptions_=on
DROP TABLE MYTABLE;
--_ignore_exceptions_=off

Method Details

createTableIfNotExists

public static boolean createTableIfNotExists(String datasourceId,
 String tableNameToCheck,
 String location,
 SourceResolver sourceResolver)
                                      throws SQLException,
IOException

This method will test if a table exists, and if not will execute a script to create it

Parameters:

datasourceId - The data source id to open a connection to the database

tableNameToCheck - The name of the table that will be checked

location - The source location where to find the script to execute to create the table. This string will be format with String.format with the dbType as argument.

sourceResolver - The source resolver

Returns:

true if the table was created, false otherwise

Throws:

SQLException - If an error occurred while executing SQL script, or while testing table existence

IOException - If an error occurred while getting the script file, or if the url is malformed
