it's a program I made but it's not used much so it still needs to be improved
MySQL doesn't have BOOLEAN/LOGICAL fields, it simulates a TINYINT field
for MEMO it's easy since it has a BLOB type
HMGCASE it's improved because I use it more, MYHMG it's more like an exercise, I don't promise but when I find time I'll fix what needs to be

Re: Grid_1 command - performance?
hi,
i wonder that nobody talk about ADO which is also used by SQLRDD
i "think" it have to do that nobody have written a CLASS, like in Fivewin, to handle "Result-Set" with ADO for GRID
---
how are a MYSSQL Server "configure"
i do NOT want to "optimise" Query, i talk about System Variable in "c:\ProgramData\MySQL\MySQL Server x.0\my.ini"
i have read about "MySQL Performance Tuning" and found e.g. these System Variable
the Website https://pgtune.leopard.in.ua/ give yuu Answer for PostgreSQL
i´m search for similar for MySQL

but which Value, depend of Hardware e.g. RAMinnodb_buffer_pool_size
max_connection
query_cache_size
innodb_io_capacity
innodb_log_file_size

the Website https://pgtune.leopard.in.ua/ give yuu Answer for PostgreSQL
i´m search for similar for MySQL
https://www.percona.com/blog/mysql-101- ... rformance/query_cache_size (> 16M)
tmp_table_size (> 32M)
max_heap_table_size (> 16M)
table_cache (> 64)
innodb_buffer_pool_size (>= 22M)
have fun

Look https://phoenixnap.com/kb/sql-query-optimization-tooli do NOT want to "optimise" Query, i talk about System Variable in "c:\ProgramData\MySQL\MySQL Server x.0\my.ini"
i have read about "MySQL Performance Tuning" and found e.g. these System Variable
Each database has its own rules on how to optimize a query, therefore general optimization is only the first step, but not enough

hi,
thx for Answer
as i say i do NOT talk about Query i talk about configure Server for MySQL
so i talk about \ProgramData\MySQL\MySQL Server x.0\my.ini
