Write (Database Engine)
Applies to:
SQL Server
Azure SQL Database
Azure SQL Managed Instance
Write writes out a binary representation of SqlHierarchyId to the passed-in BinaryWriter. Write cannot be called by using Transact-SQL. Use CAST or CONVERT instead.
Syntax
void Write( BinaryWriter w )
Arguments
w
A BinaryWriter object to which the binary representation of this hierarchyid node will be written out.
Return Types
CLR return type:void
Remarks
Write is used internally by SQL Server when it is necessary, such as when loading data from a hierarchyid column. Write is also called internally when a conversion is done between hierarchyid and varbinary.
Examples
MemoryStream stream = new MemoryStream();
BinaryWriter bw = new BinaryWriter(stream);
hid.Write(bw);
byte[] encoding = stream.ToArray();
