Query based inserting or updating of blob
However, the fact that on 32-bit GNU/Linux x86, "sort_buffer_size" must be a few Mi B only to avoid exceeding maximum process space, as explained in one infer that that sort_buffer_size is actually some kind of in-memory buffer.Additionally, the formula should probably be extended: total = innodb_buffer_pool_size key_buffer_size innodb_additional_mem_pool_size innodb_log_buffer_size max_connections * (sort_buffer_size read_buffer_size binlog_cache_size maximum_thread_stack_size); Noting that "key_buffer_size" is a My ISAM parameter there is abug in My SQL server that treat open_files_limit and open-files-limit differently also the limit for open-files-limit mentioned on this page is not entirely true appears that the "read_buffer_size" setting is used by the MEMORY table engine as the allocation increment size (minus a few bytes).
This is not documented anywhere as far as I can tell, and I only found it after banging my head against a wall looking through the My SQL source code.
If somehow, due to some sudden unexpected cataclysm, you find yourself unable to do that, then at least make the update work when blob fields are not updated. Since I already had troubles with ADO 2.0 can you please post small but complete (VS preferrable) project demonstrating this problem along with all relevant data regarding versions used. The MDAC Component Checker says I'm using "MDAC 2.8 SP1 ON WINDOWS XP SP2". Open("SELECT * FROM tst WHERE ID=1", cnn, 0, 2); rst("Name")="asd"; rst. Echo("ok"); Then you can double-click the file to run it, or execute "wscript test.js" in a command prompt. This one goes without exception: var cnn=new Active XObject("ADODB. So, should we open another bug report for v5 or modify this one? Execute("USE test") ' querying data str SQL = "SELECT * FROM tst WHERE ID=1" Dim rs Set rs = Create Object("ADODB.
If you need more details, I can upload a report with file versions. Execute("USE test"); var rst=new Active XObject("ADODB. I tried all cursor types (ad Open Dynamic, ad Open Forward Only, ad Open Keyset, ad Open Static and ad Open Unspecified) and the result is exactly the same.
