GBase8s dbaccess常用方式及技巧
A.数据库servername: testserver
B.数据库名:testdb
C.SQL脚本文件:
sqlfile.sql
create table test_table(c1 integer);
insert into test_table(c1) values(12);
update test_table set c1=0;
delete test_table where 1=1;
drop table test_table;
sqlfile2.sql
create table test_table(c1 integer);
insert into test_table(c2) values(12);
insert into test_table(c1) values(12);
update test_table set c1=0;
delete test_table where 1=1;
drop table test_table;
一.执行SQL脚本文件方式
1.调用dbaccess执行SQL脚本文件
A.简单执行SQL文件
dbaccess testdb sqlfile.sql 或者 dbaccess testdb@testserver sqlfile.sql
Database selected.
Table created.
1 row(s) inserted.
1 row(s) updated.
1 row(s) deleted.
Table dropped.
Database closed.
B.执行输出打印执行语句及执行结果
dbaccess -e testdb sqlfile.sql
create table test_table(c1 integer);
Table created.
insert into test_table(c1) values(12);
1 row(s) inserted.
update test_table set c1=0;
1 row(s) updated.
delete test_table where 1=1;
1 row(s) deleted.
drop table test_table;
Table dropped.
Database closed.
C.将执行结果重定向到文件(shell: bash)
dbaccess -e testdb sqlfile.sql > output.log > 2&1
cat output.log
create table test_table(c1 integer);
Table created.
insert into test_table(c1) values(12);
1 row(s) inserted.
update test_table set c1=0;
1 row(s) updated.
delete test_table where 1=1;
1 row(s) deleted.
drop table test_table;
Table dropped.
Database closed.
二.交互模式执行语句
dbaccess - -
> database testdb;
Database selected.
> create table test_table(c1 integer);
Table created.
> insert into test_table(c1) values(12);
1 row(s) inserted.
> update test_table set c1=0;
1 row(s) updated.
> delete test_table where 1=1;
1 row(s) deleted.
> drop table test_table;
Table dropped.
>^D
三.菜单模式执行
进入数据库
dbaccess 选择数据库
或者
dbaccess testdb
dbaccess testdb@testserver
按菜单操作执行SQL语句,其中可以使用vi进行脚本文件的编辑
四.几个小技巧
1.执行SQL脚本文件时,当出错时打印详细的错误信息
dbaccess -e -m testdb sqlfile2.sql
Database selected.
create table test_table(c1 integer);
Table created
insert into test_table(c2) values(1212);
217: Column (c2) not found in any table in the query (or SLV is undefined).
Error in line 2
Near character position 26
insert into test_table(c1) values(12);
1 row(s) inserted.
update test_table set c1=0;
1 row(s) updated.
delete test_table where 1=1;
1 row(s) deleted.
drop table test_table;
Table dropped.
Database closed.
2.执行SQL脚本文件时,当出错时打印详细的错误信息并在出现第一个错误时,停止继续执行后续的语句
dbaccess -e -m -a testdb sqlfile2.sql
Database selected.
create table test_table(c1 integer);
Table created.
insert into test_table(c2) values(1212);
217: Column (c2) not found in any table in the query (or SLV is undefined).
Error in line 2
Near character position 26
Database closed.
