you could manually create your staging table with only the fields that come with the CSV and run a select on it in MySQL Workbench. Then use the Import feature (see resultgrid toolbar) to import your CSV data.
将csv文件导入到mysql中的语句 load data infile “文件地址” into table “表名" fields terminated by ‘,’ #字段以什么符号结束 optionally enclosed by '”’ #字符串字段由双引号引起 escaped by ‘"’ #“为转义符 lines terminated by ‘\n’ #单行以\n为结束 ignore 1 lines;#不导入第一行 day...
2.2. 导入部分CSV文件 有时候,我们只需要导入CSV文件中的部分数据,而不是整个文件。在这种情况下,可以使用MySQL的LOAD DATA INFILE命令结合SET子句来指定要导入的字段和对应的值。下面是一段示例代码,演示了如何导入部分CSV文件中的数据。 LOADDATAINFILE'path/to/your/file.csv'INTOTABLEyour_tableFIELDSTERMINATEDBY'...
LOAD DATA INFILE 'data.csv' INTO TABLE table_name FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 ROWS; 参考链接 MySQL官方文档 - 数据导入 MySQL官方文档 - 导入SQL文件 通过以上信息,您应该能够全面了解MySQL数据库的import操作及其相关问题。
1. 准备CSV数据文件 确保CSV文件的格式与要导入的MySQL表的字段顺序和数据类型相匹配。 如果CSV文件包含表头(列名),确保在导入时正确设置以跳过这一行。2. 使用mysqlimport命令 mysqlimport是MySQL提供的一个命令行工具,用于将CSV文件导入到数据库中。对于100GB的大数据文件,使用mysqlimport命令时需要特别注意性能优化。
经验:使用mysqlimport快速导入csv文件 mysqlimport 工具实际上也只是“load data infile”命令的一个包装实现。 常用选项: --fields-terminated-by=字符串:设置字符串为字段之间的分隔符,可以为单个或多个字符。默认值为制表符“\t”。 -L, --local:表示从客户端任意路径读取文件导入表中,未设置该选项时,默认只...
ndb_import db_name file_name options ndb_import requires two arguments. db_name is the name of the database where the table into which to import the data is found; file_name is the name of the CSV file from which to read the data; this must include the path to this file if it ...
Importing data from CSV file directly using simple MySQL Query Here is the simplest way to do it: LOADDATAINFILE'X:/[FILE]' INTOTABLE[TABLE] Similar to Export option of MySQL it will expect file to be TAB DELIMITED if we don't specify any option for it in it's simplest form. So if...
This will help in creating the table to load the CSV file into. The first step, as stated before, is to create the table. It must have at least two columns, one a VARCHAR type and the other a MONEY type: Note: It is also possible to import the csv data to a table with more ...
This wizard only exports/imports tables using the JSON or CSV format. For an overview of the data export and import options in MySQL Workbench, see Section 6.5, “Data Export and Import”. The wizard is accessible from the object browser's context menu by right-clicking on a table and cho...
