Class JdbcConnection

For documentation of this method, see java.sql.Connection#clearWarnings().

Authorization

Scripts that use this method require authorization with one or more of the following scopes:

• https://www.googleapis.com/auth/script.external_request

Release this connection's database and all associated resources.

var conn = Jdbc.getConnection("jdbc:mysql://<host>:<port>/<instance>", "user", "password");
conn.close();

See also

• Connection.close()

Makes all pending changes permanent, releases database locks held by this JdbcConnection.

var conn = Jdbc.getConnection("jdbc:mysql://<host>:<port>/<instance>", "user", "password");
conn.setAutoCommit(false);
var stmt = conn.prepareStatement("insert into person (lname,fname) values (?,?)");
var start = new Date();
for (var i = 0; i < 5000; i++) {
  // Objects are accessed using 1-based indexing
  stmt.setObject(1, 'firstName' + i);
  stmt.setObject(2, 'lastName' + i);
  stmt.addBatch();
}
var res = stmt.executeBatch();
conn.commit(); // When this returns, this is when changes are actually committed
conn.close();

Authorization

Scripts that use this method require authorization with one or more of the following scopes:

• https://www.googleapis.com/auth/script.external_request

• Connection.commit()

For documentation of this method, see java.sql.Connection#createArrayOf(String, Object[]).

Parameters

Return

JdbcArray — An array whose elements map to the specified SQL type.

Constructs a JdbcBlob instance. See also java.sql.Connection#createBlob().

The object returned initially contains no data. You can use the setBytes methods of JdbcBlob to set the data it should contain. The blob used here is not the same as the blob created with Utilities.newBlob(data). To convert between the two formats, use the defined getBytes() and setBytes() methods. Alternatively, both JdbcBlob and JdbcClob provide a getAppsScriptBlob() convenience method for converting to a format that can be used by Apps Script.

Return

JdbcBlob — An empty blob object.

For documentation of this method, see java.sql.Connection#createClob().

Return

JdbcClob — An empty clob object.

For documentation of this method, see java.sql.Connection#createNClob().

Return

JdbcClob — An empty nclob object.

For documentation of this method, see java.sql.Connection#createSQLXML().

Return

JdbcSQLXML — An empty SQLXML object.

Creates a JdbcStatement object for sending SQL statements to the database. See also java.sql.Connection#createStatement().

// This sample code assumes authentication is off
var conn = Jdbc.getConnection("jdbc:mysql://<host>:3306/<instance>")
var stmt = conn.createStatement();

stmt.setMaxRows(100);
var rs = stmt.execute("select * from person");

while(rs.next()) {
  // Do something
}

rs.close();
stmt.close();
conn.close();

Return

JdbcStatement — A statement instance to execute queries with.
