pg_lo_write − write to a large object
pg_lo_write conn descriptor buf len
pg_lo_write writes at most len bytes from a variable buf to a large object.
conn |
The handle of a connection to the database in which the large object exists. |
descriptor
A descriptor for the large object from pg_lo_open.
buf |
The string to write to the large object (not a variable name, but the value itself). | ||
len |
The maximum number of bytes to write. The number written will be the smaller of this value and the length of the string. |
The number of bytes actually written is returned; this will ordinarily be the same as the number requested. In event of an error, the return value is negative.
