|
* 60. clobPlsqlString.js
|
|
*
|
|
* DESCRIPTION
|
|
*
|
|
* PL/SQL OUT CLOB parameters can also be bound as `STRING`
|
|
* The returned length is limited to the maximum size of maxSize option.
|
|
*
|
|
* When the types of bind out variables are not STRING or BUFFER,
|
|
* maxSize option will not take effect.
