What is _temptable?
If you have run ANALZYE, what are the contents of the sqlite_stat* tables?
What is the EXPLAI
Hello,
After re-compiling my Windows application (compiled with Visual C++ 2012, 32
Bit application) with the latest SQLite version (3.8.6) I noticed a severely
degraded performance with certain queries. The new version is 10 or more times
slower than the previous build I used (3.8.4.3).

Obviously the problem was caused by incorrectly cobbling together theSQLite
statement.
AFAICT the original code produces
UPDATE RecordGrid SET
LineNumber='',self_empty_info_gender_PRect=',,,'
WHERE RecordGridID='
Which is clearly invalid (the RHS of the WHERE condition is not terminat
Solved the problem with parameterized queries as below, without
parameterized queries the update statement doesn't work on SQLite.

Hello list,
I checked the coalesce function and observed the follwoing results:
I create a simple table with one column and one row:
create table TestTable (col_a numeric);
insert into TestTable (col_a) values (1);
commit;
The following statements retrieve the row, as expected:
select * from
SQLite is supposed to process queries as fast as possible.
Run your heavyweight queries in a dedicated thread and use your OS' way of
prioritizing threads to lessen the "felt impact" on "interactive" threads (at
the cost of increasing elapsed time).

Hi all,
Executing like query in a transaction. Query works with multiple tables
and table has 1 million records on desktop clients. CPU goes high when
transaction in progress.
Is there any way to control the CPU without adding sleep statements?
Is there any alternative solution for like
