Problem solved. Question marks shouldn´t be inside apostrophes 'SELECT * FROM chaves_de_encriptacao WHERE numero_funcional = ?' and not: 'SELECT * FROM chaves_de_encriptacao WHERE numero_funcional = ''?''' 2017-09-18 20:11 GMT-03:00 Casimiro de Almeida Barreto < casimiro.barreto@gmail.com>:

By the way, the following script fails with the same Exception (mysql_stmt_send_long_data):

| db str sttmt |

db := GADriver connectToConnectionString: 'mysql://localhost:3306/leaincertezas?user=learoot&password=welcomeLEA'.

str := 'INSERT INTO chaves_de_encriptacao (numero_funcional, chave_privada, chave_publica) VALUES (''?'', ''?'', ''?'')'.

sttmt := db prepare: str. sttmt at: 1 bind: '10'. sttmt at: 2 bind: '0BC0DE0FG32A128AB2EF01'. sttmt at: 3 bind: 'BEC0D01279F92123FAB2E0'.

sttmt execute.

db close.

But the script:

| db str sttmt |

db := GADriver connectToConnectionString: 'mysql://localhost:3306/leaincertezas?user=learoot&password=welcomeLEA'.

str := 'INSERT INTO chaves_de_encriptacao (numero_funcional, chave_privada, chave_publica) VALUES (''10'', ''0BC0DE0FG32A128AB2EF01'', ''0BC0DE0FG32A128AB2EF01'')'.

db execute: str.

db close.

Results:

MariaDB [leaincertezas]> SELECT * FROM chaves_de_encriptacao; +------------------+------------------------+------------------------+ | numero_funcional | chave_privada | chave_publica | +------------------+------------------------+------------------------+ | 10 | 0BC0DE0FG32A128AB2EF01 | 0BC0DE0FG32A128AB2EF01 | +------------------+------------------------+------------------------+ 1 row in set (0.00 sec)
