iSQL

Question

我可以使用 iSQL 连接到 SQL 服务器，但是当我测试 mysql 服务器时，它会抛出分段错误。 tsql 也有同样的问题。 Mysql服务器版本是5.7。测试了 2 个不同的 MySQL 服务器（虽然是 5.7）。

想通了。

必须下载 ODBC lib 5.2.7 然后将其复制到 libs 目录并在 odbcinst.ini 和 odbc.ini 中创建一个新条目（或将行驱动程序添加到 odbc.ini）。

wget https://cdn.mysql.com/archives/mysql-connector-odbc-5.2/mysql-connector-odbc-5.2.7-linux-debian6.0-x86-64bit.tar.gz

提取并复制 mysql-connector-odbc-5.2.7-linux-debian6.0-x86-64bit/lib/libmyodbc5*.so 到 /usr/lib/x86_64-linux-gnu/odbc/

cat /etc/odbcinst.ini

[FreeTDS]
Description=v0.63 with protocol v8.0
Driver=/usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
Setup=/usr/lib/x86_64-linux-gnu/odbc/libtdsS.so

[MySQL_ODBC]
Driver=/usr/lib/x86_64-linux-gnu/odbc/libmyodbc5w.so

cat /etc/odbc.ini

[DB01]
Driver = MySQL_ODBC
Server = 10.10.10.10
Port = 3306
TDS Version = 7.2
