Ins="insert into %s (%s) values (%s)"%(tablename, fieldlist, ph)įor k in dr.fieldnames: v.append(line)ĭb.importFromCSV("mydata.csv", "mytable")įor importing a large amount of data, you should implement transactions. Self.db.execute("CREATE TABLE %s(%s)"%(tablename, fieldlist)) Self.db.execute("DROP TABLE IF EXISTS %s"%tablename) I nedded to import many csv files, so I wrote the following python script that does the job of creating and loading sqlite tables from csv files, using the first line of the csv as the field names for the table: #!/usr/bin/env pythonĭef importFromCSV(self, csvfilename, tablename, separator=","): ![]() "IMPORT INTO TESTDB.test SELECT local_port AS port, COUNT(local_port) AS hitcount FROM connections WHERE connection_type = 'accept' GROUP BY local_port ORDER BY hitcount DESC " "CREATE TABLE TESTDB.test (name varchar(255) not null, blah varchar(255) not null) " Or: "ATTACH 'c:\directory\to\database\test.db' as TESTDB " "CREATE TABLE TESTDB.test AS SELECT local_port AS port, COUNT(local_port) AS hitcount FROM connections WHERE connection_type = 'accept' GROUP BY local_port ORDER BY hitcount DESC " So basically, you'd run (from your PHP Page): "ATTACH 'c:\directory\to\database\test.db' as TESTDB " If I run the sqLite3 tool in powershell then it works fine (sqlite3.exe 'mydatabase.db' '.read mySql.sql') But when I run the sqlite3 tool from my c code as a process, then nothing happens to mydatabase.db. You can attach a new database, create the table in it, and import to its table, so you don't have the extra step of exporting to CSV then reparsing. Im trying to run the sqlite.exe tool as a process in my c code in order to read a sql from a file. One other approach which you might not have considered is the ATTACH command. Extract the sqlite3.exe file and place it wherever you like the desktop is a good start. Where the content of import.sql is: CREATE TABLE test (name varchar(255) not null, blah varchar(255) not null) zip file for the command-line shell (not DLL or analysis). The manifest.uuid file contains the SHA3 hash of the particular check-in and is used to generate the SQLITESOURCEID macro. The Tcl script at tool/mksqlite3h.tcl does the conversion. Like so: sqlite3.exe test.sqlite < import.sql The SQLite interface is defined by the sqlite3.h header file, which is generated from src/sqlite.h.in. When I run the command in cygwin it never enters the shell it appears to hang up and I have to CTRL + C to kill it and return back to the bash command prompt.I'd recommend doing your importation from a flat file, which will create your schema followed with the actual importation: In SQLite3 developer end SQLite statement with semicolon ( ) so it automatically exit in SQLite command line but when we use system. So SQLite exit is one of the functions provided by SQLite to the user, in which we can exit from SQLite prompt. You might need to use a different extension depending on what. SQLite provides a different example for different purposes to the user. So create database and use are implied by how you run sqlite3. If dbname.sqlt exists then it will be used, if it doesn't exist then it will be created. This is what I should see: C:\Users\jmquigley\workspace\\sqlite>sqlite3Įnter SQL statements terminated with a " " If you want to create a database just name it when you run sqlite3 from the command line: sqlite3 dbname.sqlt < yoursql.sql. GNU bash, version 4.1.9(3)-release (i686-pc-cygwin)Ĭopyright (C) 2009 Free Software Foundation, Inc.ĮDIT: When I run the program from the windows command line the program works. The SQLite project delivers a simple command-line tool named sqlite3 (or sqlite3. Below are the versions of some of the relevant software. ![]() nullvalue 'text' set text string for NULL values separator 'x' set output field separator (|) Usage: C:\Windows\sqlite3.exe FILENAME įILENAME is the name of an SQLite database. Has anyone else had this issue before and if so how did you fix it? TIA. As Michael mentioned, you can also add the path of the directory containing sqlite3.exe to your PATH. Either way, I assume from your comment that sqlite3.exe is in c:\Stuff. It's as if it stops writing to the terminal when I run the shell. From your windows command prompt, you can start sqlite3 either with: cd c:\Stuff sqlite3.exe. I can see the parameters and the version. When I try to use it from the cygwin mintty terminal it seems like the program hangs. ![]() I tried the program from a windows command prompt and it works. I'm trying to use sqlite3.exe command shell with a mintty terminal in cygwin.
