Escapa una string para su uso como identificador SQL, como una tabla, una columna o un nombre de función.
|
|
Esto es útil cuando el identificador proporcionado por el usuario podría contener caracteres especiales
|
|
que no serían interpretados como parte del identificador por el analizador SQL,
|
|
o cuando el identificador podría contener caracteres en mayúsculas cuya capitalización debería preservarse.
