In this project however, I am attempting to make a JDBC wrapper and use from Android a newer version of SQLite (3.12.2) than that provided by Android 4.2.2 (3.7.11). Basically, what I have is SQLite compiled with the NDK into a static library and then a Java wrapper to provide the JDBC interfaces. My application is then attempting to use the JDBC interfaces to operate on the database. This is generally working. I can create/open databases, add/retrieve data, etc. including making use of databases that are originally created from the native android SQlite (3.7.11) I have run into a strange issue when attempting to use savepoints. I create first a transaction with "begin", then create the outer savepoint "SAVEPOINT SQLITE_SAVEPOINT_1". This savepoint will be released after 8 groups have been inserted. Next, for each of the 8 groups of data a group save point is created "SAVEPOINT SQLITE_SAVEPOINT_2", data is inserted with sqlite3_step() returning SQLITE_DONE, then savepoint is released "RELEASE SAVEPOINT SQLITE_SAVEPOINT_2" Repeat this successfully for groups 2 through 7. Group 8 however can only do 26 successful inserts and on the 27th sqlite3_step() is returning SQLITE_CANTOPEN (14). This description is of having 128 inserts per group. The exact number of inserts seems to be dependent upon the length of the text being inserted but as long as data does not change the failure point is predictable. CREATE TABLE variables (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT NOT NULL, value TEXT NOT NULL) INSERT INTO variables VALUES (null, '', '') sqlite version 3.12.2 Thanks, Jeff _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
