[英]DB2 how to get the last insert id from a table
i want to get the value of the last id insert in a table. 我想获取表中最后一个id插入的值。 How i can do this?
我怎么能这样做?
Well the solution that I use is: 那么我使用的解决方案是:
select id from NEW TABLE (insert into (val1, val2, ...) values ('lorem', 'ipsum', ...))
This gets the id column from the last row inserted in the DB :) 这从DB中插入的最后一行获取id列:)
SELECT IDENTITY_VAL_LOCAL() AS VAL FROM SYSIBM.SYSDUMMY1

// get the last inserted ID into the specified table
// int lastInsertID(string $tblName)
function lastInsertID($tblName)
{
if ($this->transIsOpen())
{
$sql = "SELECT SYSIBM.IDENTITY_VAL_LOCAL() AS id FROM " . $tblName;
$rs = $this->query($sql);
return $this->fetch($rs, "id");

resultSet = preparedStatement.getGeneratedKeys();
if (resultSet.next()) {
keyId = rs.getInt(1);
}

Update: and don't forget to create preparedStatement with the following flag Statement.RETURN_GENERATED_KEYS
