Обсуждение: pgbash-2.1 released
Hi, Please let me report that pgbash-2.1 was released. (Pgbash is a tool which can execute SQL directly with using all the functions of a bash shell. And Pgbash has functionality which is similar to psql.) * Download Page http://www.psn.co.jp/PostgreSQL/pgbash/download-e.html * Example in interactive environment ------------------- prompt> /usr/local/bin/pgbash .....Start of pgbash pgbash> connect to db2@xxx.com user sakaida; .....connect to database # PostgreSQL 7.0.0 on i386-unknown-freebsd2.2.x, compiled by gcc 2.7.x # CONNECT TO pgbash:5432 AS pgbash USER pgbash pgbash> select * from test limit 100; | more .....pipeline code|name |addr ----+----------------+-------- 1|sakaida |kobe 2|yumiko |kyoto (2 rows) pgbash> select * from test; > /tmp/sel.dat & .....redirect+background_Job pgbash> addr='Osaka' pgbash> insert into test values( > 111,'name', .....new line > '$addr' .....use shell variable > ); INSERT 22144 1 pgbash> connect to db3@yyy.com user postgres; > /dev/null pgbash> set connection db2; .....set current D/B to db2 pgbash> select * from test; &> /tmp/test.dat'.....select db2's test pgbash> ls /tmp test.dat pgbash> exec_sql -d db3 "select * from test3".....change connection to db3 pgbash> begin; BEGIN pgbash> declare cur cursor for select * from test; pgbash> fetch in cur into :AA,:BB; .....set shell variables pgbash> echo "code=$AA, name=$BB" code=1, name=sakaida pgbash> !fetch .....FETCH again pgbash> !echo .....echo again code=2, name=yumiko pgbash> end; COMMIT pgbash> disconnect all .....disconnect all connections pgbash> exit .....End of pgbash prompt> -------------------- * Example of a shell script -------------------- #!/usr/local/bin/pgbash CONNECT TO postgres; CONNECT TO dbname2 as db2 user postgres; SET CONNECTION default; SELECT * FROM test; exec_sql -d db2 "SELECT * FROM test2" # echo "key data=" read keydata # BEGIN; DECLARE cur CURSOR FOR SELECT * FROM test WHERE col1= $keydata; declares -i x; let x=0; while(( x < 100 ))do FETCH IN cur INTO :_AA :_AA_IND, :_BB ; if((SQLCODE==SQL_NOT_FOUND)); then let x=101 else if(( SQLCODE == 0 && _AA_IND != SQL_NULL )); then echo "$_AA, $_BB, $_CC" fi fi let x = x+1done fi END; echo "nFields=$SQLNFIELD FieldName=${SQLFIELDNAME[0]} .." # DISCONNECT ALL; -------------------- * Features 1. Pgbash can talk to 6.5/7.0 backend. Pgbash(+ 6.5-libpq) can talk to both 6.5 and 7.0 backend. Pgbash(+ 7.0-libpq) can talk to both 6.5 and 7.0 backend. Pgbash(+non-MB-libpq) can talk to both non-MB and MB backend. Pgbash(+ MB-libpq) can talk to both non-MB and MB backend. Here, "MB" is MULTIBYTE. 2. It is possible that pgbash manipulates multiple databases using CONNECT, DISCONNECT and SET CONNECTION (or -d option). 3. Pgbash has functionality that sets the retrieval result into the shell variable using FETCH INTO statement. 4. Pgbash has a COPY function which a general user can specify column names and a file name. (ex. COPY table( col1,..) TO '/tmp/test.dat') 5. It is possible to set CGI mode. In CGI mode, Pgbash switches the output to HTML, and read the data by GET/POST method,and read the data of HTTP_COOKIE. 6. Pgbash sets "error code", "error message", "number of tuples", etc into the shell variable. Therefore, it is possibleto know the condition after the SQL execution. -- Regards, SAKAIDA Masaaki -- Osaka, Japan # I am not good at English ;-)

Could we consider packaging pgbash into our postgres RPMs for Linux? That would make it available on a *lot* more installations, and would be a very nice addition to the RPMs. - Thomas -- Thomas Lockhart lockhart@alumni.caltech.edu South Pasadena, California

Packaging it completely separately (as, say, pgbash-2.1-1.i386.rpm) seems to make it hard to match up with other postgres-related RPMs. Does postgresql-pgbash-xxx work, or should we keep it separate? The version number is a problem if we merge it directly into the postgresql rpm set. - Thomas -- Thomas Lockhart lockhart@alumni.caltech.edu South Pasadena, California

And what create separate space for pg-family software (like pgbash, pgadmin
pgaccess ...etc)? For software which are not primary devel in pg CVS, but
we want "push" these software to distribution. Create for this software some
web space (like KDE software family) and garante for users simular names
(for example postgresql-softname-version.rpm) and for develepers that their
software will in distributions.

We currently have a similar problem with pgaccess, as its version nnumbers are not in sync with the main release. We simply ignore that difference -- but, pgaccess is a part of the core tarball. I am open to suggestions -- I could make a 'postgresql-pgbash21-7.0' series..... Kindof hokey name, though, IYKWIM. -- Lamar Owen WGCR Internet Radio 1 Peter 4:11
