postgresql - how to pass an image as paramenter to sql function -

-

i quality analysts , got task test database function n_execute() takes 3 parameters 1. image_name 2. image_data (byte array) blob type. 3. data_created problem test function want call function don't know how input iamge o second parameter of function. know can writing java code calls function wants execute through sql editor only.

you haven't mentioned database platform working in sql server t/sql script image data binary constant. simple example 0x0102030405 represents 5 hex bytes; 01, 02, 03, 04 , 05.

edit postgresql

for postgresql take @ docs, binary data types. note;

the bytea type supports 2 external formats input , output: postgresql's historical "escape" format, , "hex" format.

the postgresql equivalent sql server example e'\\x0102030405'.

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
