Insertar NULL en CSV para importarlo desde PHPMyadmin hacia MySQL

Lunes, 28 de Diciembre de 2009

Siguiendo con la importación de un Excel hacia Mysql, tenemos el problema de que los campos que no se han rellenado se insertan como “” (cadena vacía) o como 0 (cero) según sean texto o números lo que estamos insertando.

Bien, si queremos que se guarde un NULL debemos insertar el siguiente carácter: \N

Como en la anterior entrada, simple pero efectivo.

Quitar espacios entre números o palabras en excel (o calc)

Lunes, 28 de Diciembre de 2009

En una migración desde Excel a Mysql tenemos el problema de que en un campo numérico obtenemos espacios, y el entero se nos trunca. Lo que debería ser: 93 222 2222 se guarda como: 93 es decir, se trunca por el primer espacio que encuentra.

La manera más cómoda de solucionar este problema que he encontrado ha sido seleccionar la columna en cuestión y hacer un buscar/reemplazar de un espacio por nada.

Una vez hecho podemos guardar como CSV e importar desde phpmyadmin a nuetra base de datos mysql. Simple pero efectivo.
