React Higher-Order Components

A higher-order component (HOC) is an advanced technique in React for reusing component logic. HOCs are not part of the React API, per se. They are a pattern that emerges from React’s compositional nature.

function withHover(Component, propName = 'hovering') {
  return class WithHover extends React.Component {
    state = { hovering: false }
    mouseOver = () => this.setState({ hovering: true })
    mouseOut = () => this.setState({ hovering: false })
    render() {
      console.log(this.props) // { height: "16px" }
      const props = {
        [propName]: this.state.hovering,
        ...this.props,
      }
      return (
        <div onMouseOver={this.mouseOver} onMouseOut={this.mouseOut}>
          <Component {...props} />
        </div>
      );
    }
  }
}

SQL Bulk Upload

How can we avoid duplicate values while we are doing bulk insert to a table

--BEGIN TRAN
CREATE TABLE [tlg].[UserVisitLogs](
	[TStamp] 			DATETIME,
	[SessionID] 		NVARCHAR(20),
	[CorrelationID] 	NVARCHAR(20),
	[SchoolCode] 		NVARCHAR(20),
	[SiteExternalID] 	NVARCHAR(20),
	[WebType] 			NVARCHAR(20),
	[WebUrl] 			NVARCHAR(100),
	[UserSid] 			NVARCHAR(50),
	[UserName] 			NVARCHAR(20),
	[UserType] 			NVARCHAR(20),
	[CachedUser] 		NVARCHAR(20)
)
GO

-- Create Unique Clustered Index with IGNORE_DUPE_KEY=ON to avoid duplicate
CREATE UNIQUE CLUSTERED INDEX [ClusteredIndex-Logs] ON [tlg].[UserVisitLogs]
(
	[TStamp]			DESC,
	[SessionID] 		ASC,
	[CorrelationID] 	ASC,
	[SchoolCode] 		ASC,
	[SiteExternalID] 	ASC,
	[WebType] 			ASC,
	[WebUrl] 			ASC,
	[UserSid] 			ASC,
	[UserName] 			ASC,
	[UserType] 			ASC,
	[CachedUser] 		ASC
) WITH (IGNORE_DUP_KEY = ON)
GO
--ROLLBACK TRAN
