delphi programming
Budget: €30 – €250 EUR
This is an easy-to-fix task for a experienced delphi programmer
for a project to be converted, we need some VERY simple examples based on
SQLIte, LiteDAC componenets, BLOB.
examples (as simple code as possible) to:
1. create a DB (SQLite)
2. create a table and rows (for example 16 rows) which has only two fields: index (1,16 integer), array (BLOB) 3. update table rows in this table
4. read a defined row out of the table and get the BLOB data into an array
5. update the BLOB for a defined row
6. delete a row
7. delete a table
The BLOB has a fixed length and consists of the following data:
10 binary 8-bits (bytes)
+ 10 binary 16-bit (integer)
+ 10 binary 32bit (long integer)
+ 10 binary 64 bit (real)
+ 64 character ASCII string
IMPORTANT: all these routines must be done as SIMPLE as possible = no sophisticated code
Reason: for us to judge/find simplest way to convert a very old project.
