# PostgreSQL IBAN
|
|
PostgreSQL IBAN extension that can verify International Bank Account Numbers.
|
|
This ensures that only valid bank account numbers are stored.
|
|
|
|
### Example
|
|
```sql
|
|
CREATE TABLE test_iban (
|
|
name text,
|
|
account iban
|
|
)
|
|
|
|
-- Insert data
|
|
|
|
-- Dutch IBAN format
|
|
INSERT INTO test_iban (name, account) VALUES ('John', 'NL91ABNA0417164300');
|
|
-- German IBAN format
|
|
INSERT INTO test_iban (name, account) VALUES ('Doe', 'DE89370400440532013000');
|
|
|
|
-- Invalid data
|
|
INSERT INTO test_iban (name, account) VALUES ('Dean', 'AZ22NABZ00000000137010001944');
|
|
|
|
-- Show output
|
|
SELECT * FROM test_iban;
|
|
|
|
```
|
|
|
|
Manually test input
|
|
```sql
|
|
SELECT iban_validate('KW81CBKU0000000000001234560101');
|
|
-- Or cast
|
|
SELECT 'KZ86125KZT5004100100'::iban;
|
|
```
|
|
|
|
the `::iban` datatype can be cast to an text to perform string operations
|
|
```sql
|
|
SELECT 'KZ86125KZT5004100100'::iban::text;
|
|
```
