Sqline Online Conversion de Sentencias SQL,MariaDB,Oracle...

Sqline Online

Sqlines proporciona herramientas de código abierto para ayudarlo a migrar bases de datos en la nube, transferencia de datos, convertir esquema de base (DDL), vistas, procedimientos almacenados, paquetes, funciones, disparadores, consultas SQL scripts, incrustado de SQL y bases de datos del API entre base de datos.

La herramienta SQLines está disponible en las ediciones Online y Desktop:

Pros: La herramienta de migracion de sentencias que proporciona SQLines nos permite hacer cambios en distintas bases de datos con una compatibilidad y exactitud muy alta comparadas con otras herramientas online.

Contras: SQLines online no posee una API ni una linea de comandos para su uso y experimentacion de la sentencias, no posee una interfaz muy amigable ni actual(sencilla).

SQLines.com posee una alta gamma de compatibilidad con la mayoria de las bases de datos.

Ejemplos

Les daremos muestras del uso de la herramienta de conversion de sentencias, mostraremos diferentes conversiones a distintos bases de datos, como Oracle MySql, MS Sql, entre otros.

Ejemplo 1

SQL

1. CREATE FUNCTION dbo.ISOweek (@DATE datetime)
2. RETURNS int
