As per the information in Microsoft Learn on "Capacity limits for dedicated SQL pool in Azure Synapse Analytics", Database Objects section;
Dependent on column data type. Limit is 8000 for char data types, 4000 for nvarchar, or 2 GB for MAX data types; is there any way to store more than 4000 (nvarchar) characters using data type nvarchar(max)?

    Hello @Shweta Barhate ,

    Welcome to the Microsoft Q&A platform.

    Character data types that are either fixed-size, nchar, or variable-size, nvarchar.


    nvarchar [ ( n | max ) ]
    Variable-size string data. n defines the string size in byte-pairs and can be a value from 1 through 4,000. max indicates that the maximum storage size is 2^30-1 characters (2 GB). The storage size is two times n bytes + 2 bytes.

    Here is a great Stack Overflow forum posts which addressing similar issue: SQL NVARCHAR and VARCHAR Limits and How does SQL Server store more than 4000 characters in NVARCHAR(max)?.

    Hope this helps. Do let us know if you any further queries.
