“tx.executeSql”在 Expo-sqlite-storage 中无法正常工作

Question

我正在向我的应用程序添加一项功能，允许用户包含经常性费用。我将此信息存储在一个表中，该表是使用以下代码创建的：

// Creating or opening a table to store recurring expenses.
  try {
    db.transaction((tx) => {
      tx.executeSql(
        "CREATE TABLE IF NOT EXISTS rexpenses (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, amount REAL, category TEXT, startdate DATETIME DEFAULT CURRENT_TIMESTAMP, recurrancedate DATETIME, repeattype STRING);",
        [],
        () => {
          console.log("rexpenses table created successfully.");
        },
        (error) => {
          console.log("Error creating rexpenses table:", error);
        }
      );
    });
  } catch (error) {
    console.log("Error executing SQL statement in addExpense.js:", error);
  }

要将这些费用添加到表中，我使用以下函数：

function setRecurringExpense (expense) {
    
    
    const recurringInterval = expense.recurringInterval
    const date = new Date()
    let recurranceDate;

    if (recurringInterval === 'Daily') {
        recurranceDate = new Date(date.getTime() + 24 * 60 * 60 * 1000);
    } else if (recurringInterval === 'Monthly') {
        recurranceDate = new Date(date.getTime());
        recurranceDate.setMonth(date.getMonth() + 1);
    } else {
        recurranceDate = new Date(date.getTime());
        recurranceDate.setFullYear(date.getFullYear() + 1);
    }

    try {
      db.transaction((tx) => {
        tx.executeSql(
          "INSERT INTO rexpenses (name, amount, category, recurrancedate, repeattype) VALUES (?, ?, ?, ?, ?)",
          [expense.Name, expense.Amount, expense.Category, recurranceDate, recurringInterval],
          (_, { rowsAffected, insertId }) => {
            if (rowsAffected > 0) {
              console.log("Expense record inserted with ID in rexpenses:", { insertId });
            }
          },
          (_, error) => {
            console.log("Error inserting rexpense record:", error);
          }
        );
      });
    } catch(error) {
        console.log('Error adding data: ', error)
    }
}

虽然我已检查所有变量均已正确设置，但

tx.executeSql

语句无法正常工作。尽管没有记录任何错误，但它并未将费用插入表中。此外，tx.executeSql 语句之外的任何内容都会被记录，以便正确调用该函数

我尝试从表中选择数据以检查信息是否正确添加。然而，似乎

tx.executeSql

语句没有向表中添加任何内容。我花了两天时间试图找出问题的根源，但尚未找到解决方案。任何建议或帮助将不胜感激。谢谢你。

const TABLE_NAME = 'rexpenses';

export const createTablesSql = async () => {
  return await new Promise((res, rej) => {
    db.transaction(tx => {
      tx.executeSql(
        `CREATE TABLE IF NOT EXISTS ${TABLE_NAME} (
            id TEXT PRIMARY KEY AUTOINCREMENT,
            name TEXT,
            amount REAL,
            category TEXT,
            startdate DATETIME DEFAULT CURRENT_TIMESTAMP,
            recurrancedate DATETIME,
            repeattype STRING,
          );`,
        [],
        (_, result) => {
          // Table created successfully or already exists
          console.log(`Table ${TABLE_NAME} created successfully`, result);
        },
        (_, error) => {
          console.log(`Error creating table ${TABLE_NAME}`, error);
          rej(false);
        },
      );
    });
    res(true);
  });
};

export const insertDataIntoSql = async (data) => {
  return await new Promise((res, rej) => {
    db.transaction(tx => {
      tx.executeSql(
        `INSERT INTO ${TABLE_NAME} (id, name, amount, category, startdate, recurrancedate, repeattype) 
          VALUES (?, ?, ?, ?, ?, ?, ?);`,
        [
          data.id,
          data.name,
          data.amount,
          data.category,
          data.startdate,
          data.recurrancedate
          data.repeattype            
        ],
        () => res(true),
        (_, error) => {
          console.error('Insert error', error);
          rej(false);
        },
      );
    });
  });
};

// Usage:

await createTablesSql()
const inserted = await insertDataIntoSql({}) // your data here
