問題描述
我在添加數(shù)據(jù)庫(kù)時(shí)遇到了一些麻煩.
_dataBase = QSqlDatabase::addDatabase("QPSQL");調(diào)用此方法后出現(xiàn)錯(cuò)誤:
QSqlDatabase:未加載 QPSQL 驅(qū)動(dòng)程序QSqlDatabase:可用驅(qū)動(dòng)程序:QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7我包括到 PATH 變量路徑:
PostgreSQL9.3inPostgreSQL9.3libPostgreSQL9.3包括我也將文件夾 sqldrivers 復(fù)制到 Debug 文件夾.還嘗試將此文件夾中的 dll 復(fù)制到 Debug.也不行.
我來這里谷歌搜索是因?yàn)槲以?Windows 中遇到了同樣的問題.
就我而言，為了解決這個(gè)問題，我必須為 Windows 32 位安裝 PostgreSQL，因?yàn)槲业?Qt 目標(biāo)是 MinGW 32 位.
此外，我必須將 PATH 添加到 PostgreSQL bin 和 lib 目錄中，以便 Qt 可以找到正確的 .dlls.
@SET PATH=C:Program Files (x86)PostgreSQL9.6in;C:Program Files (x86)PostgreSQL9.6lib;%PATH%PATH 可以在啟動(dòng) Qt Creator 之前設(shè)置，也可以通過 Projects 窗格中的 Build Environment 使用 Qt Creator 本身.>
I have some trouble when I want to add a database.
_dataBase = QSqlDatabase::addDatabase("QPSQL");
After calling this method I have an error:
QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
I include to PATH variable paths to:
PostgreSQL9.3in
PostgreSQL9.3lib
PostgreSQL9.3include
Also I copy folder sqldrivers to Debug folder. Also tried to copy dlls drom this folder to Debug. Doesn't work either.
I came here googling because I had the same problem in Windows.
In my case to solve the issue I had to install PostgreSQL for Windows 32 bits since my Qt target was MinGW 32 bits.
Additionally, I had to add the PATH to the PostgreSQL bin and lib directories so Qt could find the right .dlls.
@SET PATH=C:Program Files (x86)PostgreSQL9.6in;C:Program Files (x86)PostgreSQL9.6lib;%PATH%
The PATH can be set before launching Qt Creator or using the Qt Creator itself via the Build Environment in the Projects pane.
