我正在尝试在我的sqlite数据库中插入日期和时间,但它无法正常工作。
这是我的数据库
CREATE TABLE `bitacora` (
`id` INTEGER,
`log` TEXT,
`nombre` VARCHAR(20),
`fecha` TEXT
);
我正在尝试以下查询;
INSERT INTO bitacora (id, nombre, log, fecha)
VALUES (1, 'ricardo carreño', 'primer post', (DATETIME('now'));

为什么不设置var并在值列表中调用它。
var DateTime = DateTime.Now;
以下是我如何插入SQLite的示例:
using System.Data.SQLite;
private void buttonAddNewItemtbl1AddButton_Click(object sender, RoutedEventArgs e)
{
var tbl1CreatedDateTime = DateTime.Now;
{
var ConnString = ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString;
using (var DbConnection = new SQLiteConnection(ConnString))
{
try
{
const string insertIntotbl1TableString = "INSERT INTO [tbl1] (tbl1ID, tbl1EnvironmentType, tbl1URL, tbl1Server, tbl1CreatedDate, tbl1Deleted) VALUES (@tbl1ID, @tbl1EnvironmentType, @tbl1URL, @tbl1Server, @tbl1CreatedDate, @tbl1Deleted)";
var insertIntotbl1Table = new SQLiteCommand(insertIntotbl1TableString);
insertIntotbl1Table.Connection = DbConnection;
insertIntotbl1Table.Parameters.AddWithValue("@tbl1ID", Guid.NewGuid().ToString());
insertIntotbl1Table.Parameters.AddWithValue("@tbl1EnvironmentType", ComboBoxtbl1EnvironmentType.Text);
insertIntotbl1Table.Parameters.AddWithValue("@tbl1URL", TextBoxtbl1Url.Text);
insertIntotbl1Table.Parameters.AddWithValue("@tbl1Server", TextBoxtbl1ServerName.Text);
insertIntotbl1Table.Parameters.AddWithValue("@tbl1CreatedDate", tbl1CreatedDateTime);
insertIntotbl1Table.Parameters.AddWithValue("@tbl1Deleted", "0");
try
{
DbConnection.Open();
insertIntotbl1Table.ExecuteNonQuery();
DbConnection.Close();
MessageBox.Show("Successfully added");
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
}
在我的app.config中,它看起来像这样:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<connectionStrings>
<add name="ConnString" providerName="System.Data.SQLite" connectionString="Data Source=C:\Temp\SQLiteDB.db"/>
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1"/>
</startup>
</configuration>

一位朋友帮我修复了查询句子。
应该如下:
INSERT INTO bitacora(id,nombre,log,fecha)VALUES(1,'ricardocarreño','primer post',DATETIME('now'));
