Sqlite3 pyqt5和python3
inpsearch = ('%'+self.lineEdit.text()+'%',)
conn = sqlite3.connect('formuladatabase')
c = conn.cursor()
c.execute('DROP TABLE IF EXISTS search')
c.execute('CREATE TABLE search(rowid, Name TEXT, Surname TEXT, datestamp TEXT, Stylist TEXT, formula TEXT, Price REAL)')
这是原作下面的工作
#c.execute('INSERT INTO search SELECT * FROM clientsformula WHERE Name LIKE ?', inpsearch)
一栏工作得很好，但我希望通过2栏搜索
c.execute('INSERT INTO search SELECT * FROM clientsformula WHERE Name=? OR Surname=?', inpsearch, inpsearch)
此返回：类型错误函数最多需要2个参数（3）
conn.commit()
c.close()
conn.close()
希望解决这个问题好几天......还有一个侧面问题是否有人知道如何使用Pyqt5为QlineEdit制作自动完成（.setCompleter）
谢谢

$.fn.dataTable.ext.search.push(
function( settings, data, dataIndex ) {
var mini = document.getElementById('datepicker').value;
var maxi = document.getElementById('datepicker2').value;
var mini2 = document.getElementById('datepicker3').value;
var maxi2 = document.getElementById('datepicker4').value;
if((mini !== '') && (maxi !== '')){
var taena = data[10]; // use data for the date column
var ifMin = mini.substring(0,2) + mini.substring(3,5) + mini.substring(6,10);
var ifMax = maxi.substring(0,2) + maxi.substring(3,5) + maxi.substring(6,10);
var ifTaena = taena.substring(0,2) + taena.substring(3,5) + taena.substring(6,10);
if ( ( ifMin === '' && ifMax === '' ) || ( ifMin === '' && ifTaena <= ifMax ) || ( ifMin <= ifTaena && ifMax === '' ) || ( ifMin <= ifTaena && ifTaena <= ifMax ) ){
return true;
}
return false;
}
if((mini2 !== '') && (maxi2 !== '')){
var taena2 = data[9]; // use data for the date column
console.log(taena2);
var ifMin2 = mini2.substring(0,2) + mini2.substring(3,5) + mini2.substring(6,10);
var ifMax2 = maxi2.substring(0,2) + maxi2.substring(3,5) + maxi2.substring(6,10);
var ifTaena2 = taena2.substring(0,2) + taena2.substring(3,5) + taena2.substring(6,10);
if ( ( ifMin2 === '' && ifMax2 === '' ) || ( ifMin2 === '' && ifTaena2 <= ifMax2 ) || ( ifMin2 <= ifTaena2 && ifMax2 === '' ) || ( ifMin2 <= ifTaena2 && ifTaena2 <= ifMax2 ) ){
return true;
}
return false;
}
return false;
}
);
需要2个参数，sql语句和参数元组（在你的情况下是2个绑定值）。您提供sql语句和2个元组和1个参数。
这应该有效：
cursor.execute()或者：
bv = '%'+self.lineEdit.text()+'%'
inpsearch = (bv, bv, )
c.execute('INSERT INTO search SELECT * FROM clientsformula WHERE Name=? OR Surname=?', inpsearch)
