Ce script génère des instructions d'insertion de vos données existantes. Il s'agit d'une procédure stockée que vous devez exécuter une fois, puis elle est conçue sur mesure pour vous.
J'ai essayé de trouver ce genre de choses pendant un certain temps, mais je n'étais pas satisfait des résultats, j'ai donc écrit cette procédure stockée.
Exemple:
Exec [dbo].[INS] 'Dbo.test where 1=1'
(1) Voici le dboschéma et le test est un nom de table et 1=1est une condition.
Exec [dbo].[INS] 'Dbo.test where name =''neeraj''' * for string
(2) Voici le dboschéma et le test est un nom de table et name='neeraj'est une condition.
Voici la procédure stockée

Example (1) Exec [dbo].[INS] 'Dbo.test where 1=1'
(2) Exec [dbo].[INS] 'Dbo.test where name =''neeraj''' * for string
here Dbo is schema and test is tablename and 1=1 is condition
